A 10 kg block is pulled in the vertical plane along a frictionless surface in the form of an arc of a circle of radius 10m. The applied force is 200N as shown in the figure. If the block started from rest at A, the velocity at B would be:

A

The speed at Q is `20 m//s`.

B

The speed at Q is `20 sqrt( 3) m//s`

C

The speed at Q is `10 sqrt( 3) m//s`.
