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

`4g`

Text Solution

Verified by Experts

Acceleration due to gravity `g. (GM)/(R^(2))`
If the mass and radius of the earth are both doubled
` g. (G(2M))/((2R)^(2)) = (2GM)/(4R^(2)) = 1/2 ((GM)/(R^(2))),g. = g/2 `
