The value of g at a particular point is ...

The value of `g` at a particular point is `10 m s^(-2)`. Suppose the earth shrinks uniformly to half of its present size without losing any mass. The value of `g` at the same point (assuming that the distance of the point from the centre of the earth does not change) will now be

A

`4.9 m//s^2`

B

`3/1 m//s^(2)`

C

`9.8m//s^(2)`

D

`1/9.6 m//s^(2)`
