Question

Calculate acceleration due to gravity at A. at a height 16 km above the earth surface & B ad depth 12. s km below the surface of earth. given Radius of ecorth = 6400 km Acceleration due to gravity on the surface of earth = 9.8 m/s2​

Answer 1

Answer:

Explanation:

1. Acceleration due to gravity,  g = 9.8ms-2 , Height h = 16 × 103m Radius of the earth,  R = 6400 × 103 m From the equation g1 = g  ( R R + h ) 2 (RR+h)2 = 9.8  ( 6400 × 10 3 6400 × 10 3 + 16 × 10 3 ) (6400×1036400×103+16×103) = 9.75 ms-2 2. depth, h = 2.8 × 103m From the equation g1 = g  [ 1 − h R ] [1−hR] = 9.8  [ 1 − 2.8 × 10 3 6400 × 10 3 ] [1−2.8×1036400×103] = 9.796 ms-2
