A rod of length L is pivoted at one end ...

A rod of length L is pivoted at one end and is rotated with as uniform angular velocity in a horizontal plane. Let `T_1 and T_2` be the tensions at the points L//4 and 3L//4 away from the pivoted ends.

A

`T_1gtT_2`

B

`T_2gtT_1`

C

`T_1=T_2`

D

The relation between `T_1 and T_2` depends on whether the rod rotates clockwise or anticlockwise.
