Question

Acceleration due to gravity increases as we move away from the surface of the earth radially towards the sky.

(a) True

(b) False

This question was posed to me at a job interview.

Origin of the question is Acceleration due to Gravity below and above the Surface of Earth topic in division Gravitation of Physics – Class 11

Answer 1

Correct answer is (b) False

Explanation: The volume or mass enclosed by the radius vector from the centre of the earth remains the same as we move higher from the earth’s surface. However, the increase in radius decreases the acceleration due to gravity. The mathematical relationship is as follows;

g = (G*M1)/R^2;

M1 = Mass of the earth

R = Radius vector from the centre of the earth.
