4 A solid sphere of radius R and dielectric constant
K has spherical cavity of radius
.A point charge
4
9, is placed in the cavity. Another charge q, is
placed outside the sphere at a distance of r from
g., then coulombic force of interaction between
them is found to be F,. When the same charges
are separated by same distance in vacuum, the
force of interaction between them is found to be F
then
(1) F
(2) F
(3) F, F,=V +
(4) F, = F2
