The mass and diameter of a planet have twice the value of the corresponding parameters of the earth. Acceleration due to gravity on the surface of the planet is

A

`9.8m//s^(2)`

B

`19.6m//s^(2)`

C

`980m//s^(2)`

D

`4.9m//s^(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
As , `g=(GM)/(R^(2)),g.=(G(2M))/((2R)^(2))`
`thereforeg.=(1)/(2),g=(9.8)/(2)=4.9m//s^(2)`
