Apair of opposite electric charges of equal magnitude is called a(n) a) dipole. b) point charge. c) electric field. d) field line.

A) dipole.

Explanation:

As we know that when two equal and opposite charges are placed at some distance from each other then this combination of two equal and opposite charges are known as electric dipole.

Here electric dipole has dipole moment which is a vector quantity which is measured as the product of charge and distance between the two charges

it is given as

here the direction of dipole moment is from negative charge to positive charge.

so correct answer is given as

A) dipole.
