Question

If the acceleration on the surface of earth is 9.8.if earth is shrinked 1/3 of its size. Then what is the acceleration due to gravity ?​

Answer 1

Answer:

new volume = 1 /3 original volume

4/3 πr'³ =1/3( 4/3 π r³)

r'³ = 1/3 r³

(r'/r)³ = 1/3

(r'/r)² = 1/3⅔

g' = g x 3⅔

= 9.8 x 3⅔ m/s²

Answer 2

Answer:

Answer:

new volume = 1 /3 original volume

4/3 πr'³ =1/3( 4/3 π r³)

r'³ = 1/3 r³

(r'/r)³ = 1/3

(r'/r)² = 1/3⅔

g' = g x 3⅔

= 9.8 x 3⅔ m/s²
