Q1. What is the electric field 0.60 m away from a small sphere with a positive charge of 1.23×10^(−8) C?
Q2. Two charges, one of 3.2×10^(−9) C, the other of −6.4×10^(−9) C, are 42 cm apart. Calculate the net electric field at a point P, 15 cm from the positive charge, on the line connecting the charges.
Q3. Calculate the magnitude and direction of the electric field at point Z in the figure below, due to the charged spheres at points X and Y.
