A platform P is moving with a velocity `v_p` over hemispherical shell. A vertical rod AB passing through a hole in the platform is moving on the shell and remains vertical. There is sufficient friction between rod and shell to stop the slip. C is the crown of the shell and O is its centre `angleBOC = theta` at any instant. Find the velocity of point B in downward motion at that instant.

A

`upsilon_(p) sin theta`

B

`upsilon_(p) cos theta`

C

`upsilon_(p) tan theta`

D

`upsilon_(p) cot theta`
