The force experienced by the charges when they are placed 2 m apart will be 0.25 N.
The force between two charges is given by Coulomb’s Law.
According to this law, the force between two charges varies inversely as the square of the distance between the charges and is directly proportional to the product of the magnitude of the two charges.
The above statement is represented by the following equation,
F= K Q1 x Q2/r^2
Here, F = Force between the two charges
K = Constant
Q1 and Q2 = Magnitude of the two charges
r = Separation between the two charges
According to this equation, the force is inversely proportional to the square of the distance between two charges.
Initially, when the two charges are 1 m apart, the force is 1 N.
When the distance between the two charges is doubled,
then according to Coulomb’s Law, the force should decrease by 4 times.
Hence, if the charges are placed 2 meters apart, the force becomes 1/4= 0.25 N.
