A particle of mass m is attached to a vertical rod with two inextensible strings AO and BO of equal lengths l. Distance between A and B is also l. The setup is rotated with angular speed `omega` with rod as the axis.

Options

A. Tension in thread BO is greater
B. Tension in thread AO is greater
C. Tension in the two threads are equal
D. Tension in AO or BO is greater according as `omega` is anticlockwise or clockwise

Answer

B

Explanation

`T_(1) sin 30^(@) = T_(2) sin 30^(@) + mg implies t_(1) = T_(2) + 2 mg`
`implies `T_(1) gt T_(2)`
