An electron is moving around infinite linear positive charge in the orbit of 0.1 m. If the linear charge density is 1 muC//m , the velocity of electron will be

In which atomic model positive charge contributes to almost all mass of atom?

Two spherical , nonconducting and very tin shells of uniformly distributed positive charge Q and radius d are located a distance 10d from each other . A positive point charge q is placed inside one of the shells at a distance d//2 from the center, on the line connecting the centers of the two shells , as shown in the figure, What is the net force on the charge q ? .

Consider a neutral conducting sphere. A positive point charge is placed outside the sphere. The net charge on the sphere is then

A small sphere of radius r_(1) and charge q_(1) is enclosed by a spherical shell of radius r and charge q_(2) Show that if q_(1) is positive, charge will necessarily flow from the sphere to the shell (when the two are connected by a wire) no matter what the charge q_(2) on the shell is.

If the total charge enclosed by a surface is zero, does it imply that the electric field everywhere on the surface is zero ? Conversely, if the electric field everywhere on a surface is zero, does it imply that net charge inside is zero.

When charge is given to a soap bubble, it shows:Two equal negative charges -q are fixed fixed at point (0, -a) and (0,a) on y-axis. A positive charge Q is released from rest at the point (2a, 0) on the x-axis. The charge Q will:
