Track OABCD (as shown in figure ) is smooth. What minimum speed has to be given to a particle lying at point A, so that it can reach point C? (take `g=10 m//s^2`)

A

60 m/s

B

100 m/s

C

70 m/s

D

80m/s

Text Solution

Verified by Experts

The correct Answer is:
D
Minimum speed is required to enable the particle to reach at B.By energy conservation
`1/2 mv^(2) =mgh`.
By putting values v =80 m/s
