A bob of mass 10 M is suspended through ...

A bob of mass 10 M is suspended through an inextensible string of length I. When the bob is at rest at the equilibrium position, two particles of mass m each moving with velocity u making an angle 60° with the string strike and get simultaneously attached to the bob. What is the value of impulsive tension (Jtension) be string during the impact?

A

Zero

B

2 mu

C

mu

D

12 mu

Text Solution

Verified by Experts

The correct Answer is:
C

`J_"tension"= 2 Jcos 60°`
And `J = mu`
`J_"tension"= 2 (mu) • 1/2` = mu
