Q1. A 4 kg fish swimming 3 m/s swallows an absent minded 2 kg fish at rest. What is the speed of the large fish instantly after lunch?
Q2. Given three parallel conducting plates, that is aligned perpendicular to the x-axis. They are labelled, from left to right as plate 1, 2 and 3 respectively. The corresponding plate charges are Q1 = -q, Q2 = 0 and Q3 = q. The width of the gap between 1 and 2 is d, and the width between plates 2 and 3 is d/2. Determine the magnitude of the potential difference across 1 and 3.
