An electron is revolving in a circular path of radius 2xx10^(-10) m with a speed of 3xx10^(6) m/s. The magnetic field at the centre of circular path will be-

A particle is moving on a circular path of radius R with constant speed v. During motion of the particle form point A to point B

If a charged particle having charge q is moving in a circular path of radius R with a uniform speed u, what would be the magnetic field at the centre?

An electron is moving in a circle of radius r in a uniform magnetic field B. Suddenly the field is reduced to B/2 . The radius of the circular path now becomes.

In a homogeneous magnetic field B there is an electron moving in a circular orbit with a speed v. Find the ratio of the magnetic field generated by the moving electron at the middle of the circle and the magnetic field making it revolve.
