I posted this Q earlier and I got the result also,but I don't able to understand it by equation only,so can you please explain it with diagram please pleaseQ-A rod of mass M and length l is held horizontal when it is released. The angular velocity of the rod at an instant it is making an angle of 450 with horizontal(only tell me how to calculate decrease in potential energy with diagram plssss)
