I. The electric potential 0.35 m from a point charge is +110 V. Find the magnitude and sign of the electric charge. 2. Charge (71 is 0.16 m from point A. Charge '32 is 0.40 m from pointA. The electric potential at A iszero. Calculate the ratio of the two charges. 02 3. Draw two equal positive point charges and connect them with a line. (a) Is there a point on the line at which the electric field is mere? (b) Is there a point on the line at which the electric poten- tial is zero? (c) Explain the difference between the two answers
