A charge `Q` is fixed at a distance `d` in front of an infinite metal plate. The lines of force are represented by

A charge + Q is fixed at a distance d in front of an infinite metal plate. Draw the lines of force indicating the directions clearly.

Two point charge Q and 4Q are fixed at a distance of 12cm from each other. Sketch lines of force and locate the neutral point, if any .

Assertion. If a point charge q is placed in front of an infinite grounded condcuting plane surface, the point charge will experience a force. Reason. This force is due to the induced charge on the conducting surface which is at zero potential

Two connected charges of +q and -q respectively are at a fixed distance AB apart in a non uniform electric field whose lines of force are shown in the figure The resultant effect on the two charges is
