The value of $‘g’$ at a particular point is $9.8\,m/{s^2}$. Suppose the earth suddenly shrinks uniformly to half 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 earth does not shrink) will now be ......... $m/{\sec ^2}$.

$g = \frac{{GM}}{{{r^2}}}$. Since $M$ and $r$ are constant, so $g = 9.8\,\,m/{s^2}$
