A charge q is suspended from the ceiling with the help a massless and inextensible string. When an electric field of 20 × 105 V/m is applied horizontally, the charge displaces towards the electric field, and at the equilibrium the string is making an angle of 30o with the vertical and the tension in the string is found to be 10 N. Find the value of the charge q.
