A mass `'m' kg` is whirled in a verticle plane by tying it at the end of a flexible wire of length `'L'` and area of cross-section `'A'` such that it just completes the verticle circle. When the mass is a its lowest positon, the strain produced in the wire is (Young's modulus of the wire is `'Y'`)

`AY//6mg`

`6mg//AY`

`5mg//Ay`

`AY//5mg`

Text Solution

Verified by Experts

The correct Answer is:

`F = 6mg`, strain `= (F)/(AY)`
