Question

Two uniformly charged plates are pictured below, with four evenly spaced points shown along a horizontal line between the plates.
What is the correct rank of the strength of the electric field at the points, greatest first?

• A. $1,2,3,4$
• B. $4,3,2,1$
• C. The electric field strength is the same at all points
• D. $1$ and $4$ tie, $2$ and $3$ tie
• E. $2$ and $3$ tie, $1$ and $4$ tie

Answer 1

The correct option is C The electric field strength is the same at all points

The electric field in between the plates is $E=\frac{\sigma }{{ϵ}_0}$

Thus, the field in between the plates is uniform and it is independent of distance. So, the field at every point in between the plates will be same.

Thus, the answer will be option C.
