Question
In one model of the election, the mass of electron m_{e} is thought to be a uniformly charged shell of radius R and total charge e, whose electrostatic energy E is equivalent to its mass m_{e} via Einstein’s mass energy relation E = m_{e}c^{2}. In this model, R is approximately – (m_{e} = 9.1 × 10^{31}kg, c = 3 × 10^{8} ms^{1}, magnitude of the electron charge = 1.6 × 10^{19} C)

Question
At a distance l from a uniformly charged long wire, a charged particle is thrown radially outward with a velocity u in the direction perpendicular to the wire. When the particle reaches a distance 2l from the wire its speed is found to be. The magnitude of the velocity, when it is a distance 4l away from the wire, is (ignore gravity)
