(D) The formula for centripetal force is $F_c = \frac{mv^2}{r}$.Given $F_c = 10 \, N$ and $r = 20 \, cm = 0.2 \, m$.Substituting the values: $\frac{mv^2}{0.2} = 10$.This implies $mv^2 = 10 \times 0.2 = 2 \, J$.The kinetic energy $K$ is given by $K = \frac{1}{2}mv^2$.Substituting $mv^2 = 2$,we get $K = \frac{1}{2} \times 2 = 1 \, J$.
