Q1. Charge of uniform density (80 nC/m^3) is distributed throughout a hollow cylinder region formed by two coaxial cylindrical surfaces of radii 1.0 mm and 3.0 mm. Find out the magnitude of electric field at a point which is 2.0 mm from symmetry axis.
Q2. An alpha particle (m = 6.7 x 10^-27kg, q = +3.2 x 10^-19C) has a speed of 30km/s at point A and moves to point B where it momentarily stops. Only electric forces act on the particle throughout this motion. Find out the electric potential difference.
