Acceleration due to gravity is g on the surface of the earth. The value of acceleration due to gravity at a height of 32 km above earth's surface is (Radius of the earth = 6400 km )

Question

Acceleration due to gravity is g on the surface of the earth. The value of acceleration due to gravity at a height of 32 km above earth's surface is (Radius of the earth = 6400 km ), 0.9 g, 0.99 g, 0.8 g, 1.01 g

MARKS App · Accepted Answer

h = 32 k m , R = 6400 k m , so h R g ′ = g 1 - 2 h R = g 1 - 2 × 32 6400 ⇒ g ′ = 99 100 g = 0.99 g
