Q.1) Three point charges, two positive and one negative, each having a magnitude of 20 uC are placed at the vertices of an equilateral triangle (30 cm on a side). What is the magnitude of the electrostatic force on the negative charge?

2) 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. Determine the magnitude of the electric field at a point which is 2.0 mm from the symmetry axis.

3) An alpha particle (m = 6.7 x 10^-27kg, q = +3.2 x 10^-19C) has a speed of 20km/s at point A and moves to point B where it momentarily stops. Only electric forces act on the particle during this motion. Determine the electric potential difference.
