Hello All !
I have this question which I cant seem to get the correct ans to.. maybe Im missing something.. (Please refer to attachment)
POtential energy = mass x g x h
The Attempt at a Solution
ok initial amt of energy = m x g x h
final energy state =( mgh/4 + mgh/4 )= mgh/ 2
so mgh - mgh/2 = mgh/2 (my ans)
apparently correct ans is mgh/4
help , pls ? thanks !
