If the mass and radius of the Earth are ...

If the mass and radius of the Earth are both doubled, then the accelration due to gravity g

A

remains same

B

`(g)/(2)`

C

2g

D

4 g

Text Solution

Verified by Experts

The correct Answer is:
C
Acceleration due to gravity , `g= (GM)/(R^2)`
If mass and radius of the earth is halved
`therefore g. =(G(M/2))/((R/2)^2) = (4GM)/(2R^2) = 2g`
