Question

A hemisphere is uniformly charged positively. The electric field at a point on a diameter away from the centre is directed (A) perpendicular to the diameter (B) parallel to the diameter (C) at an angle tilted towards the diameter (D) at an angle tilted away from the diameter

When the point is on the diameter and away from the centre of hemisphere which is charged uniformly and positively, the component of electric field intensity parallel to the diameter cancel out. So the electric field is perpendicular to the diameter.

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

perpendicular to the diameter

parallel to the diameter

at an angle tilted towards the diameter

at an angle tilted away from the diameter

When the point is on the diameter and away from the centre of hemisphere which is charged uniformly and positively, the component of electric field intensity parallel to the diameter cancel out. So the electric field is perpendicular to the diameter.
