The electrical force between 2 objects is 400 N. According to Coulomb's law, if both charges are doubled, the electrical force will be 1600 N.
The electrical force between 2 charged objects is directly proportional to their charges and inversely proportional to the square of the distance between them.
The electrical force between 2 objects is 400 N. Due to the direct proportionality, if the charge of both objects is doubled (multiplied by 2), the total force will be multiplied by 4.
F = 2 × 2 × 400 N = 1600 N
