A simple pendulum of length L and mass (...

A simple pendulum of length L and mass (bob) M is oscillating in a plane about a vertical line between angular limit `-phi` and `+phi`. For an angular displacement `theta(|theta|ltphi)`, the tension in the string and the velocity of the bob are T and V respectively. The following relations hold good under the above conditions:

A

T =Mg cos `theta`

B

T cos `theta`=Mg

C

`T-"Mg cos" theta=(Mv^(2))/(L_`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
The bob moves on a circular path

`therefore" "T-mg cos theta=(Mv^(2))/(L)`
