Application +4 | -1

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

{30^\mathrm{o}}

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

1.6g\;c{m^{ - 3}},

the dielectric constant of the liquid is

View answer and explanation

Correct option: D

Option D (2) is correct because the dielectric constant is calculated using the ratio of the density of the sphere to the difference between the density of the sphere and the density of the liquid.
