A hemisphere is uniformly charged positively. The electric field at a point on a diameter away from the centre is directed

Given data:

The hemisphere is uniformly positively charged. The electric field goes from the center to a point on the diameter

Concepts used: Electric field

Explanation:

If the point lies on the diameter and away from the center of a uniform, positively charged hemisphere, the components of the electric field strength parallel to the diameter cancel out. Therefore the electric field is perpendicular to the diameter.
