A small particle of mass \( m \) attached with a light inextensible thread of length \( \mathrm{L} \) is moving in a vertical circle. In the given case particle is moving in complete vertical circle and ratio of its maximum to minimum velocity is \( 2: 1 \).
P
Kinetic energy of the particle at the lower most position is:
(1) \( \frac{4 \mathrm{mgL}}{3} \)
(2) \( 2 \mathrm{mgL} \)
(3) \( \frac{8 \mathrm{mgL}}{3} \)
(4) \( \frac{2 \mathrm{mgL}}{3} \)
