If the density of small planet is that of the same as that of the earth while the radius of the planet is 0.2 times that of the Earth, the gravitational acceleration on the surface for the planet is` ........`

A

`0.2`g

B

`0.4g`

C

2g

D

4g

Text Solution

Verified by Experts

`g = 4/3 pi GRrho and g. = 4/3piGR.rho , (g.)/g = (R.)/R = 0.2 rArr g. = 0.2 g `
