A pendulum is made of a massless string of length L and a small bob of negligible size and mass m. It is released making an angle q0 (<<1 rad) from the vertical. When passing through the vertical, the string slips a bit from the pivot so that its length increases by a small amount d(d << L) in negligible time. If it swings up to angle q1 one the other side before starting to swing back, then to a good approximation which of the following expressions is correct?
  • a)
  • b)
  • c)
  • d)
Correct answer is option 'D'. Can you explain this answer?

U can use energy conservation twice here to get some equations
and u will also get another equation if u apply conservation of angular momentum when the Bob slips by small distance about the pivot
