Questions
A body is hanging from a rigid support by an inextensible string of length I. It is struck inelastically by an identical body of mass m with horizontal velocity , the tension in the string increases just after striking by {AFMC 2012]
detailed solution
Correct option is C
Tension in the string,T=2mv'2l+2mg=m(2gl)2l+2mg∵2mv'2l= Centrifugal force and v'=v2=gl2∴ Increase ill tension = 3 m g-m g=2 m gTalk to our academic expert!
