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.

Construct an isosceles triangle in which the lengths of each of its equal sides is 6.5 cm and the angle between them is 110^@

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 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 charged metal sphere A and B are situated in a vaccum. The distance between the centres of the spheres is 12.0 cm, as shown in the fig. The charge on each sphere may be assumed to be a point charge at the centre of the sphere. Point P is a movable point that lies on the line joining the centres of the sphere and is distance x fromt he centre of sphere A. The variation with distance x fo the electric field strength E at point P as shown in the figure. State the evidence provided by in the fig for the statement that the spheres are conductors, the charges on the spheres are either both positive or both negative.

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^@ ?

Two small charged metal sphere A and B are situated in a vaccum. The distance between the centres of the spheres is 12.0 cm, as shown in the fig. The charge on each sphere may be assumed to be a point charge at the centre of the sphere. Point P is a movable point that lies on the line joining the centres of the sphere and is distance x fromt he centre of sphere A. The variation with distance x fo the electric field strength E at point P as shown in the figure. Use fig to state and explain the distance x at which the rate of change of potential with distance is maximum and minimum.

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 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?
