A collar B of mass 2kg is constrained to move along a horizontal smooth and fixed circular track of radius 5m. The spring lying in the plane of the circular track and having spring constant 200N/m is undeformed when the collar is at A. If the collar starts from rest at B the normal reaction exerted by the track on the collar when it passes through A is :
  • a)
    720N
  • b)
    2880N
  • c)
    1440N
  • d)
    360N
Correct answer is option 'C'. Can you explain this answer?
