Problem
The Figure on the right shows the electric field lines for two point objects separated by a small distance. The charges q₁ and q₂ can be identified as
(a) q₁ is positive; q₂ is negative; q₁/q₂ = -3;
(b) q₁ is negative; q₂ is positive; q₁/q₂ = -3;
(c) q₁ is positive; q₂ is negative; q₁/q₂ = -1/3;
(d) q₁ is negative; q₂ is positive; q₁/q₂ = -1/3;
(e) q₁ is zero with charges redistributed over the surface of the object 1 due to electrostatic induction; q₂ is positive.
