Q. 8

Two charged particles are placed at a distance 1.0 cm apart. What is the minimum possible magnitude of the electric force acting on each charge?

Answer :

Given: missing


For the electric force to be minimum, the magnitude of charge on the particles must be minimum. As both the particles are charged, they must have non-zero minimum charge.


Hence, they both must carry charge having magnitude of fundamental unit of charge i.e. 1.6 × 1019 C.


Magnitude of charges,


Distance between the charged particles,


________________________________________________


Formula used:


By Coulomb’s law, the electric force is given by:



Where ϵ0 is the permittivity of free space


k is the electrostatic constant


q1 and q2 are the magnitude of charges


r is the distance of separation between the charges
