1. ASSERTION : The difference in the value of acceleration due to gravity at pole and equator is proportional to square of angular velocity of earth. REASON : The value of acceleration due to gravity is minimum at the equator and maximum at the pole.

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!

2. ASSERTION : A needle placed carefully on the surface of water may float, whereas the ball of the same material will always sink. REASON : The buoyancy of an object depends both on the materials and shape of the object.

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!

3. ASSERTION : During rapid pumping of air in tyres, air inside the tyre is hotter than atmospheric air. REASON : Adiabatic process occurs at very high rate.

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

6. ASSERTION : Sound waves cannot propagate through vacuum but light waves can. REASON : Sound waves cannot be polarised but light waves can be.

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!

7. ASSERTION : If an electron and proton possessing same kinetic energy enter an electric field in a perpendicular direction, the path of the electron is more curved than that of the proton. REASON : Electron forms a larger curve due to its small mass.

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!

9. ASSERTION : Two parallel wires carrying current in the same direction attract each other because of potential difference between them. REASON : The potential difference between two parallel current carrying conductor produce an acceleration.

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.
