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_(1) gt T_(2)`

B

`T_(2) gt T_(1)`

C

`T_(1) = T_(2)`

D

The relation between `T_(1)` and `T_(2)` depends on whether the rod rotates clockwise or anticlockwise.
