11 Two identical non conducting solid spheres of same mass

Last updated: 6/9/2023

11 Two identical non conducting solid spheres of same mass and charge are suspended in air from common point by two non conducting massless strings of same length At equilibrium the ang between the strings is a The spheres are now immersed in a dielectric liquid of density 800 kg m and dielectric constant 21 If the angle between the strings remains the same after the immersio then A electric force between the spheres remains unchanged B electric force between the spheres reduces ma mass density of the spheres is 840 kg m 3 D the tension in the strings holding the spheres remains unchanged
