Q1. The potential at location A is 393 V. A positively charged particle is released there from rest and arrives at location B with a speed vB. The potential at location C is 781 V, and when released from rest from this spot, the particle arrives at B with twice the speed it previously had, or 2vB. Find potential at B.
Q2. On level ground a shell is fired with the initial velocity of 74.5m/s at 60.5deg above the horizontal and feels no appreciable air resistance. At its highest point, find out the horizontal and vertical components of its velocity.
