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)

• A. 0.9 g
• B. 0.99 g
• C. 0.8 g
• D. 1.01 g

Answer 1

Answer: (B)

0.99 g

Answer 2

, , so

$g ^ { \prime } = g \left( 1 - \frac { 2 h } { R } \right)$ $= g \left( 1 - \frac { 2 \times 32 } { 6400 } \right)$⇒
