A body of mass $\displaystyle 100$ g is moving in circular path of radius $\displaystyle 2$ m on vertical plane as shown in figure. The velocity of the body at point A is $\displaystyle 10 \mathrm{~m} / \mathrm{s}$. The ratio of its kinetic energies at point B and C is :
(Take acceleration due to gravity as $\displaystyle 10 \mathrm{~m} / \mathrm{s}^2$ )
(Take acceleration due to gravity as $\displaystyle 10 \mathrm{~m} / \mathrm{s}^2$ )Official answer
From NTA’s final answer key for this paper.
