Two small spheres each of mass 10 mg are suspended from a poimt by threads 0.5 m long. They are equally charged and repel each other to a distance of 0.28 m. If `g = 10 ms^-2`, what is the charge on each ?

Two small spheres each of mass 10^6kg are suspended from a point by silk threads 50 cm long. These are equally charged and repel each other to a distance of 20 cm apart. Calculate the charge on each sphere. Take g = 10 ms^-2

Two pith-balls each weighing 10^-3 kg are suspended from the same point by mans of silk threads 0.5 m long. On charging the pith-balls equally, they are found to repel each other to a distance of 0.2 m. Calculate the charge on each ball?

Two pith-balls each of mass 5xx10^-4 kg are suspended from the same point by silk threads 0.2 m long equal charges are given to the balls, which separate, until the threads enclose an angle of 30^@ , Calculate the charge on each pith-ball.

Two small spheres each having mass m kg and charge q coulomb are suspended from a point by insultaing threads each l metre long but of negligible mass. If theta is the angle, each string makes with the vertical when equilibrium has been attained show that q^2 = (4m g l^2 sin ^2 theta tan theta) 4 pi upsilon_0

A small cork ball with a mass 0.58 g is suspended from a thread 10 cm long. Another ball is fixed at a distance 10 cm from the point of suspension and at a distance of 5 cm from the thread as shown in the figure What shoud the magnitude of the like and equal charges on the balls be t deflect the thread through 30^@ ?

Three particles, each of mass 1g and carrying a charge q , are suspended from a common point by insulating massless strings , each 100 cm long . if the particles are located at the corners of an equilateral triangle of side 3 cm, calculate the charge q on each particle.

A small metal ball of mass m is suspended from a thread of length l between the plates of a large plane capacitor. How will the period of oscillations of such a pendulum change, if a charge + q is placed on the ball and the upper plate is negatively charged?

A small metal ball of mass m is suspended from a thread of length l between the plates of a large plane capacitor. How will the period of oscillations of such a pendulum change, if a charge + q is placed on the ball and the upper plate is positively charged

Two similar small metallic spheres are suspended by eal threads from the same point. When either sphere is given a similar charge of 36 statC. The distance between them is 6 cm. If the length of each thread is 5 cm, find the mass of each sphere and the tension in each thread.
