Answer 1

Answer:

Two charged spheres separated at a distance d exert a force f on each other. if they are immersed in a liquid of dielectric constant 2, then what is the force(if all condition are same)

Answer 2

Answer : F/2

Solution:

Given :

Distance between two charges = d and dielectric constant (k) = 2. Force between two charged spheres (F) = 14πε0×q1q2r2, where e0 is permitivity of free space. Force for amedium with dielectric constant k,

F′=1k×14πε0×q1q2r2=Fk=F/2
