Q1. A 2.47 kg steel ball strikes a massive wall at 11.7 m/s at an angle of alpha = 67.2° with the plane of the wall. It bounces off with the same speed and angle. If the ball is in contact with the wall for 0.218 s, what is the magnitude of average force exerted on the ball by the wall?

Q2. Find out the breakdown voltage for an argon filled chamber having electrode separation of 0.3 cm and first Townsend coefficient of 100 cm^-1 at STP. What would be the breakdown voltage if the gas in the chamber is replaced by helium?
