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)`
