Two charge spheres separated at a distance d exert a force F on each other. If they are immersed in a liquid of dielectric constant K=2, then the force (if all conditions are same) is

Two tiny charged spheres separated in air by a distance exert a force 'F'on each other .If they are immersed in a liquid of dielectric constant 2,then the force is

Two charged spheres separated •at a distance 'd' exert a force of 5 N on each other. If they are immersed in a liquid df dielectric constant 2, the force becomes :

Two charges spheres are separated at a distance d exert a force F on each other, if charges are doubled and distance between them is doubled then the force is

Two charges spheres are separated at a distance d exert a force F on each other . If charges are doubled and distance between them is doubled then the force is a)F b)F/2 c)F/4 d)4F

Two charges spheres are separated at a distance d exert a force F on each other . If charges are doubled and distance between them is doubled then the force is a)F b)F/2 c)F/4 d)4F

Mutual electrostatic force F is acting on two tiny charged spheres, when they are d distance apart in air.Keeping the external conditions fixed, if the spheres are immersed in a liquid of dielectric constant 2 , then the force acting on each sphere becomes
