If the radius of the earth were to shrink by one percent its mass remaining the same, the acceleration due to greavity on the earth's surface would

A

decrease

B

remain unchnaged

C

increase

D

be zero

Text Solution

Verified by Experts

The correct Answer is:
C
`g=(GM)/(R^(2)) g'=(GM)((0.9R)^(2))`
`:.g'/g=((R^(2))/(0.99R))^(2)impliesg'gtR`
