two identical charged spheres are suspended by strings of equal length. Each string makes an angle theta with the vertical. When suspended in a liquid of density p is equal to 0.8 g/cc, the angle remains the same. What is the dielectric constant of the liquid?(density of the material of sphere is 1.6 g/cc) IN THIS QUESTION I WANT TO ASK THAT WHAT WILL BE THE WEIGHT OF BALLS WHEN THEY ARE SUSPENDED IN THE LIQUID AND HOW?

Dear Abhishek 

There weight less than the weight in air due buyancy force exerted by liquid.
