Two identical charged spheres are suspended by strings of equal lengths. The strings make an angle of

{30^ \circ }

with each other. When suspended in a liquid of density

0.8g

c{m^{ - 3}},

the angle remains the same. If density of the material of the sphere is

1.6

g

c{m^{ - 3}},

the dielectric constant of the liquid is
