One end of a string of length 1 m is tied to a body of mass `0.5` kg. It is whirled in a vertical circle with angular velocity 4 rad `s^(-1)`. Find the tension in the string when the body is at the lower most point of its motion. (take, g = 10 `ms^(-1)`)

A

3 N

B

5 N

C

8 N

D

13 N

Text Solution

Verified by Experts

The correct Answer is:
D
Tension, `T=momega^(2)r+mg`

`=0.5xx(4)^(2)xx1+0.5xx10=13N`
