1.	A mass m kg is whirled in a vertical plane by tying it at the end of a flexible wire of length l and area of cross section 'A'. When the mass is at its lowest position the strain produced in the wire is, if Youngs modulus of the wire is 'Y' (if V= sqrt( 5 gl ) )
Answer» `(AY)/(6 MG) ` `( 6 mg)/( AY)` `( 5 mg)/( AY)` `(AY)/( 5mg)` ANSWER :B
