Oops I mean from the part which is stationary
Isn’t the rod accelerating overall? Why would any part be stationary ?
Will any part be stationery I mean net force is acting on the rod right so it would accelerate.
Btw bro. Your method of dividing at L/2 will give same answer for total extension as integrated answer
Oh I got it what I was doing wrong , thx a lot guys ( I think integration is best now )
Yeah @Viraam_Rao @Azimuddin_Sheikh
It will give same answer as the tension for the half part on which 2F acts will be 3F and for the part where 3F acts tension will be 2F. So it's just like two half rods for same situation.
So for finding PE, we have to integrate ?
No other method right
Right now yes I guess, unless someone comes with a magical soln.
Yeah bro likely I think so . although I believe there is another one using only that energy formula . I will just go through my physics copy tomorrow will tell u if I get it with that energy formula
