A string of length ' L ' fixed at one end carries a body of mass ' m ' at the other end. The mass is revolved in a circle in the horizontal plane about a vertical axis passing through the fixed end of the string. The string makes angle ' ' with the vertical. The angular frequency of the body is ' '. The tension in the string is
Options
- AmL ^2
- BmL ^2
- C^2 ~mL
- Dm ^2 L
Correct answer
B. mL ^2
Step-by-step solution
In case of conical pendulum, the tension in the string provides the necessary centripetal force. T = mr ^2= mL ^2 ( Here, r = L )
