Physics - Circular Motion Question with Solution | TestHub

A body of mass$1 \mathrm{kg}$is connected to a string and is undergoing a complete vertical circular motion of radius$1 \mathrm{m}$. If it is barely able to complete the vertical circle, then the difference in its kinetic energy at the top and bottom of the circle is (Take$g=10\mathrm{ }\mathrm{m}{\mathrm{s}}^{-2}$)
