An electric field is uniform and in the ...

An electric field is uniform and in the positive x direction for positive x and uniform with the same magnitude but in the negative x direction for negative x. It is given that `E=200 hat(i) N//C` for `x gt 0` and `E=-200 hat(i) N//C` for `x lt 0`. A right circular cylinder of length 20 cm and radius 5 cm has its centre at the origin and its axis along the x-axis so that one face is at `x=+10` cm and the other is at `x=-10` cm
What is the flux through the side of the cylinder?

Text Solution

Verified by Experts

For any point on the side of the cylinder E is perpendicular to `Delta S` and hence `E. Delta S=0`. Therefore, the flux out of the side of the cylinder is zero.
