Question

True or False?

1. Location A is at origin. Location C is at (4, 0) and Location B is at (4,3) . The E field is along the x direction. Location A and C have the same potential.

2. Location A is at origin. Location C is at (4, 0) and Location B is at (4,3) . The E field is along the x direction. Location B and C have the same potential.

3. Location A is at origin. Location C is at (4, 0) and Location B is at (4,3) . The E field is along the x direction. The potential change from A to B is equal to -Ed, where d=4.

4. Electric potential due to a point charge, at distance r, is proportional to 1/r2 .

5. The equipotential surfaces associated with a uniform E field consist of a family of planes that are perpendicular to the E field.

6. The electric potential difference between two points can exist when there is only a source charge. Even when there is no TEST charge q, the potential difference can exist between two points in the space.

Explanation / Answer

1. False

In the direction of the electric field, electric potential decrease. Electric field is a negative gradient of potential. hence A is at high potential than B. Electric field is along the x-axis
