(a) Given is a line of charge of uniform linear density. A charge +q is distributed uniformly between y = 0 and y = a and charge -q is distributed uniformly between y = 0 and y = -a. Explain how the direction of the resultant electric field at point P can be obtained. Represent using a vector diagram. (b) Two point charges 4Q, Q are separated by 1 m in air. At what point on the line joining the charges is the electric field intensity zero?
