If in the previous problem, the breaking strength of the string is `2mg`, then the minimum tension in the string will be

The tension in the string is:

In the previous problem, If the string C is stretched slowly, then

A bob of mass m is suspended from a fixed support with a light string and the system with bob and support is moving with a uniform horizontal acceleration. The breaking strength of the string is mg sqrt(2) . Find the workdone by the tension in the string in the first one second :

A pendulum consisting of a small sphere of mass m, suspended by a inextensible and massless string of length 1 , is made to swing in a verticle plane. If the breaking strength of the string is 2 mg, then the maximum angular amplitude of the displacement from the verticle can be
