Three small balls, each of mass 10 gm are suspended separately from common point. by silk threads, each one meter long. The balls are identically charged and hang at the corners of an equilateral triangle of side 0.1. metre. Find the charge on each ball?

Charge of 5 mu C each are placed at the corners of an equilateral triangle of side 10 cm. Then the force on each charge is :-

Three charges each 20muC are placed at the corners of an equilateral triangle of side 0.4m The potential energy of the system is

At each corner of an equilateral triangle identical charges are placed. Then at the centre of the triangle

Three paricles, each of mass m and carrying a charge q each, are suspended from a common pointby insulating massless strings each of length L. If the particles are in equilibrium and are located at the corners of an equilateral triangle of side a, calculate the charge q on each particle. Assume Lgtgta .

Two small spheres, each having a mass of 20 g, are suspended form a common point by two insulating strings of length 40 cm each. The spheres are identically charged and the speration between the balls at equilibrium is found to be 4 cm . Find the charge on each sphere.

Two pith balls,, each weighting 10mg are suspended from the sam point by silk threads, each of length 0.25m. When equal and similar charges are placed on them they repel each other and are 10m apart. Find the charge on the each pith ball.

Two small spheres each of mass m are suspended from a common point by threads 0.5 m long. They are equally charged and repel each other to a distance of 0.28m. If =g10ms^(-2) , what is the charge on each sphere?

Three identically charged, small spheres each of mass m are suspended from a common point by insulated light strings each of length I. The spheres are always on vertices of an equilateral triangle of length of the sides x (ltlt l) . Calculate the rate dq/ dt with which charge on each sphere increases if length of the sides of the equilateral triangle increases slowly according to law (dx)/(dt)=(a)/(sqrt(x))
