Two point charges +q and -q are placed at distanced d apart. What are the points at which the resultant field is parallel to the line joininin the two charges?

Two point charges Q and -3Q are placed at some distance apart. If the electric field at the location of Q is E, then field at the location of -3Q is

Two point charge q_A=3muC and q_b=-3muC are located 20 cm apart in vacuum.What is the electric field at the midpoint 0 of the line AB joining the two charge ?

Two point charge of 20muC and 80muC are placed 18cm apart .Find the position where the electric field is zero.

Two point charges q_1 and q_2 are separated by a distance r in space:-What happens to the force between the charges:-When the magnitude of the point charge Increases.

Two point charges q_1 and q_2 are separated by a distance r in space What happens to the force between the charges, i) When the magnitude of one of the point charges is doubled. ii) When the distance of separation is halved.

Two point charges q_1 and q_2 are sepa-rated by a distance r in space:- What happens to the force between the charges:- When the distance of separation is decreased. Hence establish the law governing it.

Two equal and opposite charge +q and -q are separated by a small distance 2a. Br Name this arrangement.

Two charges Q and q are placed at a distance ‘d’ from each other. If the magnitude of each charge is doubled and the distance between them halved, the force becomes?
