Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R. Assertion A: If we move from poles to equator, the direction of acceleration due to gravity of earth always points towards the center of earth without any variation in its magnitude. Reason R: At equator, the direction of acceleration due to gravity is towards the center of earth. In the light of above statements, choose the correct answer from the options given below (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) A is false but R is true.

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. A is false but R is true.

Correct answer: A is false but R is true.

Solution

Assertion A is incorrect because the magnitude of gravitational acceleration does vary from the poles to the equator due to the Earth's rotation and its shape, while Reason R is correct as it accurately states that at the equator, gravity points towards the center of the Earth.
