Q1

An object is performing vertical circular motion. If its velocity at the topmost point is given by:

\({v}_{\text{top}}=n\sqrt{gl},\ n>1\)

Determine the ratio of the kinetic energy at the bottom to that at the top.​

a

\(\frac{{n}^{2}+4}{{n}^{2}}\)​

b

\(\frac{{n}^{2}}{{n}^{2}+4}\)​

c

\(\frac{{n}^{2}+2}{{n}^{2}}\)​

d

\(\frac{{n}^{2}}{{n}^{2}+2}\)​
