Question

In order to just complete the vertical circular motion, the ratio of kinetic energy of a particle at highest point to that at lowest point is, 5, 2, 0.5, 0.2

MARKS App · Accepted Answer

K.E = 1 2 m v 2 At lowest point in vertical circular motion V l = 5 r g and at highest point V h = r g ∴ K . E h K . E l = 1 5 = 0.2
