+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.i was able to get the answer by conserving momentum and then applying COME but isme kya galat hai
any1?
i think thats for a particle connected to the end of a massless rod, for this u gotta derive it using 1/2 * I * w^2 = mgl
ohh ok
got it thanks
