Problem
Charge over a nonconducting ring is distributed so that the linear charge density varies as λ=λ0sinθ. What is the direction of force on a charge q0 placed at the center?
(1) along 1 if q0 is positive and 2 if q0 is negative
(2) along 2 if q0 is positive and 1 if q0 is negative
(3) along 3 if q0 is positive and 4 if q0 is negative
(4) along 4 if q0 is positive and 3 if q0 is negative
