Question

If the electric field at a point is along the south, the potential gradient is zero:-

(1) along north
(2) along south
(3) along north-east
(4) along east and west

Answer 1

Answer:

2 along south is the answer

Answer 2

Hey Dear,

◆ Answer -

(4) along east and west

● Explaination -

As we know,

• potential gradient perpendicular to the electric field is zero.
• potential gradient parallel to the electric field is maximum.

Here, electric field is pointing towards south, so potential gradient will be zero at

• east
• west
• up
• down

Thanks dear. Hope this helps you..
