Three particle of mass m each are placed...

Three particle of mass `m` each are placed at the three corners of an equilateral triangle of side a. Find the work which should be done on this system to increase the side of the triangle to `2a`.

Text Solution

Verified by Experts

The correct Answer is:
9
At any time t,
`omega=(usin60^(@))/(x)`
`alpha=(usin60^(@))/(x^(2))((dx)/(dt))`
`alpha=(usin60^(@))/(x^(2))(u+u cos 60^(@))`
`alpha at t=0`
`alpha=(u sin 60^(@))/(a^(2))(u+u cos 60^(@))`=9 rad/`s^2`
