2 identical charges are suspened by strings of equal length , the strings make an angle of 30° with each other when suspended in a liquid of density 800kg/m³. the angle remains the same what is the di-electric constant of the liquid , the density of the material of the sphere is 1000kg/m³

Di-electric constant K = density of ball/(density of ball - density of liquid ) K= 1000/(1000-800) = 1000/200 = 5
