The electrostatic force on a small sphere of charge 0.4muC due to another small sphere of charge -0.8muC in air is 0.2N What is the force on the second sphere due to the first ?

The mass of a metal sphere charged with +20 esu is 2g. Another smaller sphere with -128 esu of charge is suspended with a thread. The former sphere, just below this smaller one, is at rest. What is the distance between the centres of the two spheres? g="980 cm . s"^(-2)

Two identical spheres, each of mass m, are suspended from a point by threads. Each sphere carries a charge q. If the angle between the threads is very small, prove that in equilibrium, the distance between the centres of the two spheres is, x=((q^(2)l)/(2pi epsilon_(0)mg))^((1)/(3))

A uniformly charged conducting sphere of 2.4 m diameter has a surface charge.density of 80.0muC//m^2 What is the total electric flux leaving the surface of the sphere ?

Two sphere M and N, having charge q_(1) and q_(2) are kept at some distance from each other.q amount of charge is taken from the sphere M and transferred ot the sphere N. What is the new charge of the two spheres so that the force acting between them becomes maximum?

Two insulated metal spheres of the same size are charged with -15 esu and +25 esu. The distance between their centres is 10 cm. What is the force acting between the two charges? If the two spheres are made to touch each other and then placed in their previous positions, what will be the force acting between them?

If a solid large sphere is made by melting three small gold-sphere of radii 3 mm , 4mm, and 5mm, then what will be the radius of the large sphere?

The electrostatic potential on the surface of a charged conducting sphere is 100 V. Two statement are made in this regard - S_(1) : At any point inside the sphere, electric intensity is zero. S_(2) : At any point inside the sphere, the electrostatic potential is 100V. Which of the following is a correct statement?
