Question

an electric field E=5i V/m exists in the space taking potential at origin be 0 the potential at the pt. A(2,2,1) will be

Answer 1

Answer ⇒ $E = 5 \hat{i}$

Explanation ⇒ As per as the question we can see that in equation of Electric field there is no variable x,y and z.

∴ Electric field will be same everywhere.

$E = 5 \hat{i}$

Now, Electric filed will only be in x direction.

You can easily understand why electric filed is zero on origin. Since, electric filed line will be drawn perpendicular to x axis and parallel to x axis. At Origin x = 0. Thus, E = 0.

Thus, electric filed is zero at the origin. Otherwise at each and every point , it will be same.

Thus, Electric field at point P is also given by,

$E = 5 \hat{i}$

Hope it helps.
