An insect jumps from ball A onto ball B,...

An insect jumps from ball A onto ball B, which are suspended from inextensible light strings each of length `L=8cm`. The mass of each ball and insect is same. What should be the minimum relative velocity (in `ms^-1`) of jump of insect w.r.t. ball A, if both the balls manage to complete the full circle?

Text Solution

Verified by Experts

The correct Answer is:
`(8)`
For completing the full circle:

`u/2=sqrt(5gL)impliesu=4ms^-1`
Relative velocity `=2u=8ms^-1`
