Question
The figure show a nonconducting ring which has positive and negative charge non uniformly distributed on it such that the total charge is zero. Which of the following statements is true ?
Options
A.The potential at all the points on the axis will be zero.
B.The electric field at all the points on the axis will be zero.
C.The direction of electric field at all the points on the axis will be along the axis.
D.If the ring is placed inside a uniform external electric field then net torque and force on acting on the ring would be zero.
Solution
Potential at any point is a scalar quantity.
∵ Positive charge = negative charge i.e., the net Electric is equal is a vector quantity so it depends not only distance but also the way of distribution of charge.
∵ Positive charge = negative charge i.e., the net Electric is equal is a vector quantity so it depends not only distance but also the way of distribution of charge.
