A pendulum bob swings along a circular path on a smooth inclined plane as shown in figure, where `m=3kg`, `l=0.75m`, `theta=37^@`. At the lowest point of the circle the tension in the string is `T=274N`. Take `g=10ms^-2`.

The tension in the string at the highest position is

A

(a) `166N`

B

(b) `67.66N`

C

(c) `68N`

D

(d) `152N`

Text Solution

Verified by Experts

The correct Answer is:
A
`T_H+mg sin 37^@=(mv_H^2)/(l)impliesT_H=166N`
