A body of mass 
hangs at one end of a string of length l , the other end of which is fixed. It is given a horizontal velocity so that the string would just reach where it makes an angle of 
with the vertical. The tension in the string at mean position is

Text Solution
Verified by ExpertsThe correct answer is:
A
When body is released from the position p (inclined at angle q from vertical) then velocity at mean position
\ \ Tension at the lowest point =
