A particle of mass m is tied at the end ...

A particle of mass m is tied at the end of a light string of length L, whose other end is fixed at point C (fig), and is revolving in a horizontal circle of radius r to form a conical pendulum. A parallel horizontal beam of light forms shadow of the particle on a vertical wall.

If the tension in the string is F find -
(a) The maximum acceleration of the shadow moving on the wall.
(b) The time period of the shadow moving on the wall.

Text Solution

Verified by Experts

The correct Answer is:
`(a) (1)/(m)sqrt(F^(2)-(mg)^(2)), (b) 2pi((m^(2)r^(2))/(F^(2)-(mg)^(2)))^(1//4)`
