Two opposite charges are placed on a line as shown in the figure below3qThe charge on the right is three times the magnitude of the charge on the left. Besidesinfinity, where else can electric field possibly be zero?2. A right isosceles triangle of side a has charges q, +2q and -q arranged on its vertices,as shown in Figure.What is the electric fieldpoint P, midway between the line connecting the +q and -gcharges? Give the magnitude and direction of the electric field.3. Four point charges are placed at the corners of a square of side a, as shown in Figure.
