Problem

At three neighbouring regions

P

Q

and

R

in an electrostatic field, successive equipotential surfaces differ by

10\,\text{V}

. The separation between the same pair of successive surfaces is

0.5\,\text{mm}

P

1\,\text{mm}

Q

and

2\,\text{mm}

R

. Which one of the following correctly represents the magnitude of the electric field

|E|

at these regions? a)

|E|_{\text{R}} > |E|_{\text{Q}} > |E|_{\text{P}}

|E|_{\text{Q}} > |E|_{\text{P}} > |E|_{\text{R}}

|E|_{\text{P}} > |E|_{\text{Q}} > |E|_{\text{R}}

|E|_{\text{P}} = |E|_{\text{Q}} = |E|_{\text{R}}
