A meter stick, of mass 400 g, is pivoted at one end displaced through an angle 
. The increase in its potential energy i
Text Solution
Verified by ExpertsThe correct answer is:
A
Centre of mass of a stick lies at the midpoint and when the stick is displaced through an angle 60 o it rises upto height ‘h’ from the initial position.
From the figure 
Hence the increment in potential energy of the stick = mgh
