Application +4 | -1

The electric field in a certain region is given by

\vec{E}=5 \hat{i}-3 \hat{j} k V / m.

The potential difference

V_B-V_A

between points

A

and

B,

having coordinates

(4,0,3) \,\mathrm{m}

and

(10,3,0) \,\mathrm{m}

respectively, is equal to

View answer and explanation

Correct option: B

-21 \,\mathrm{kV}

Option B (

-21 \,\mathrm{kV}

) is correct because the potential difference is calculated by integrating the electric field along the path between the two points.

Assertion:- Electric field lines do not cut at any point.
Reason:- At any point, there is only one direction of electric field. Statement-I: A positive point charge is brought in an electric field, the electric field at neary by point will increase
