A solid sphere uniformly charged has a long smooth

Question

A solid sphere uniformly charged has a long smooth tunnel passing through it, at a distance of r from the centre of the sphere(assume it to be a chord). A charged particle -Q,mass m is released in the tunnel at a distance x from the centre of the tunnel. Find the time required by the particle to reach the centre of the tunnel if charge of the sphere is Q and radius is R.

Arun Kumar · Accepted Answer

Distance of chord from center = rRadius of Sphere = RDistance of particle from center of tunnel = xDistance of particle from centerNow the electric field effective on that particle will be with a sphere of above radius and charge proptional to volume of sphere with above volume(Apply Gauss law)But the direction of this force will be radial .So Take tunnel direction component.Divide by mass to get acceleration.Then get the time.Thanks & RegardsArun KumarIIT DelhiAskiitians Faculty
