Given below are two statements:
 Assertion (A): There is no effect of rotation of earth on acceleration due to gravity at poles. Reason (R): Rotation of earth is about the polar axis.

 1 Both (A) and (R) are true and (R) is the correct explanation of (A). 2 Both (A) and (R) are true but (R) is not the correct explanation of (A). 3 (A) is true but (R) is false. 4 Both (A) and (R) are false.

Given below are two statements:

 Assertion (A): Generally the path of a projectile from the Earth is parabolic but it is elliptical for a projectile going to a very great height. Reason (R): At the ordinary height, the projectile moves under a uniform gravitational force, but for great heights, the projectile moves under a variable force.

 1 Both (A) and (R) are True and (R) is the correct explanation of (A). 2 Both (A) and (R) are True but (R) is not the correct explanation of (A). 3 (A) is True but (R) is False. 4 Both (A) and (R) are False.

Given below are two statements:
 Assertion (A): A body becomes weightless at the centre of the earth. Reason (R): As the distance from the centre of earth decreases, acceleration due to gravity increases.

 1 Both (A) and (R) are true and (R) is the correct explanation of (A). 2 Both (A) and (R) are true but (R) is not the correct explanation of (A). 3 (A) is true but (R) is false. 4 Both (A) and (R) are false.

Given below are two statements:
 Assertion (A): At the pole, the value of acceleration due to gravity (g) is greater than that at the equator. Reason (R): Earth rotates on its axis in addition to revolving around the sun.-
