प्रश्न
A point charge + q is placed at a distance d from an isolated conducting plane. The field at a point P on the other side of the plane is ______.
विकल्प
directed perpendicular to the plane and away from the plane
directed perpendicular to the plane but towards the plane
directed radially away from the point charge
directed radially towards the point charge
उत्तर
A point charge + q is placed at a distance d from an isolated conducting plane. The field at a point P on the other side of the plane is directed perpendicular to the plane and away from the plane.
Explanation:
If a point positive charge is placed near an isolated conducting plane, free electrons are attracted towards the positive charge. Result of this some negative charge develops on the surface of the plane towards the positive charge side and an equal positive charge develops on the opposite side of the plane. The electric field lines are away from the positive charge and perpendicular to the surface.

A positive charge Q is uniformly distributed along a circular ring of radius R. A small test charge q is placed at the centre of the ring (figure). Then
- If q > 0 and is displaced away from the centre in the plane of the ring, it will be pushed back towards the centre.
- If q < 0 and is displaced away from the centre in the plane of the ring, it will never return to the centre and will continue moving till it hits the ring.
- If q < 0, it will perform SHM for small displacement along the axis.
- q at the centre of the ring is in an unstable equilibrium within the plane of the ring for q > 0.
