Q Two point charges separated by a certain distance in vacuum
exerts an electrostatic force on each other of magnitude 4 ×
10 - 3   N What will be the magnitude of force between the
charges in a dielectric medium of k=2 while separated by same
distance?

Dear student,

F=14πε0q1q2r2In the presence of dielectricF'=14πε0kq1q2r2so F'=Fk=4×10-32F'=2×10-3N
