A gun is firing 20 balls per seconds of mass 20 gm each on the smooth horizontal table surface ABCD. If the collision is perfectly elastic and balls are striking at the centre of table with a speed 5 m/sec at an angle of 60° with the vertical just before collision, then force exerted by one of the leg on ground is (assume total weight of the table is 0.2 kg and g = 10 m/s2) :
  • a)
    0.75 N
  • b)
    0.25 N
  • c)
    0.5 N 
  • d)
    1 N
Correct answer is option 'D'. Can you explain this answer?
