b) Both ASSERTION and REASON Are True but REASON Is Not the Correct Explanation of ASSERTION

c) ASSERTION Is True but REASON Is False

d) Both ASSERTION and REASON are False.

Correct! Wrong!

ASSERTION : A transistor amplifier in common emitter configuration has a low input impedance. REASON : The base to emitter region is forward biased.

a) Both ASSERTION and REASON Are True and REASON Is the Correct Explanation of ASSERTION

b) Both ASSERTION and REASON Are True but REASON Is Not the Correct Explanation of ASSERTION

c) ASSERTION Is True but REASON Is False

d) Both ASSERTION and REASON are False.

Correct! Wrong!

ASSERTION : In general, speed is greater than the magnitude of the velocity. REASON : The magnitude of average velocity is greater than the average speed.

a) Both ASSERTION and REASON Are True and REASON Is the Correct Explanation of ASSERTION

b) Both ASSERTION and REASON Are True but REASON Is Not the Correct Explanation of ASSERTION

ASSERTION : The apparent weight of a body in an elevator moving with some downward acceleration is less than the actual weight of a body. REASON : The part of the weight is spent in producing downward acceleration, when body is in elevator.

a) Both ASSERTION and REASON Are True and REASON Is the Correct Explanation of ASSERTION

b) Both ASSERTION and REASON Are True but REASON Is Not the Correct Explanation of ASSERTION

c) ASSERTION Is True but REASON Is False

d) Both ASSERTION and REASON are False.

Correct! Wrong!

ASSERTION : The work done in bringing a body down from the top to the base along a frictionless inclined plane is the same as the work done in bringing it down the vertical side. REASON : The gravitational force on the body along the inclined plane is the same as that along the vertical side.

a) Both ASSERTION and REASON Are True and REASON Is the Correct Explanation of ASSERTION

b) Both ASSERTION and REASON Are True but REASON Is Not the Correct Explanation of ASSERTION

c) ASSERTION Is True but REASON Is False

d) Both ASSERTION and REASON are False.

Correct! Wrong!

ASSERTION : There are very small sporadic changes in the period of rotation of the Earth. REASON : Shifting of large air masses in the earth’s atmosphere produce a change in the moment of inertia of the Earth causing its period of rotation to change.

a) Both ASSERTION and REASON Are True and REASON Is the Correct Explanation of ASSERTION

b) Both ASSERTION and REASON Are True but REASON Is Not the Correct Explanation of ASSERTION

c) ASSERTION Is True but REASON Is False

d) Both ASSERTION and REASON are False

Correct! Wrong!

ASSERTION : The universal gravitational constant is same as acceleration due to gravity. REASON : Gravitational constant and acceleration due to gravity have same dimensional formula.

a) Both ASSERTION and REASON Are True and REASON Is the Correct Explanation of ASSERTION

b) Both ASSERTION and REASON Are True but REASON Is Not the Correct Explanation of ASSERTION

c) ASSERTION Is True but REASON Is False

d) Both ASSERTION and REASON are False.

Correct! Wrong!

ASSERTION : All the raindrops hit the surface of the earth with the different constant velocity. REASON : An object falling through a viscous medium eventually attains a terminal velocity.

a) Both ASSERTION and REASON Are True and REASON Is the Correct Explanation of ASSERTION

b) Both ASSERTION and REASON Are True but REASON Is Not the Correct Explanation of ASSERTION

c) ASSERTION Is True but REASON Is False

d) Both ASSERTION and REASON are False.

Correct! Wrong!

ASSERTION : A piece of ice, with a stone frozen inside it, floats on water in a beaker. When the ice melts, the level of water in the beaker decreases. REASON : Density of stone is more than that of water.

a) Both ASSERTION and REASON Are True and REASON Is the Correct Explanation of ASSERTION

b) Both ASSERTION and REASON Are True but REASON Is Not the Correct Explanation of ASSERTION

c) ASSERTION Is True but REASON Is False

d) Both ASSERTION and REASON are False.

Correct! Wrong!

ASSERTION : The total translational kinetic energy of all the molecules of a given mass of an ideal gas is 1.5 times the product of its pressure and its volume. REASON : The molecules of a gas collide with each other and the velocities of the molecules change due to collision.

a) Both ASSERTION and REASON Are True and REASON Is the Correct Explanation of ASSERTION

b) Both ASSERTION and REASON Are True but REASON Is Not the Correct Explanation of ASSERTION

c) ASSERTION Is True but REASON Is False

d) Both ASSERTION and REASON are False.
