If the distance between two point charges its increased by a factor of four, the magnitude of the electrostatic force between them will be

Answer Details

According to Coulomb's law, the electrostatic force between two charges is inversely proportional to the square of the distance between them. Therefore, if the distance between two charges is increased by a factor of four, the force between them will decrease by a factor of 16 (4^2). Therefore, the answer is: 1/16 of its former value.
