Suppose a uniform electric field exists in the room in which

Suppose a uniform electric field exists in the room in which you are working, such that the
lines of force are horizontal and at right angles to one wall. As you walk toward the wall
from which the lines of force emerge into the room, are you walking toward
(a) Points of higher potential?
(b) Points of lower potential?
(c) Points of the same potential (equipotential line)?

can someone explain this question to me step by step without using chegg textbook solutions.

Solution

Since you are walking towards the lines of force which are emerging into the room therefore the correct option is (a)

(a) Points of higher potential
