A conducting sphere of radius a = 50 cm is grounded with a resistor R = 152 as shown below. The sphere is exposed to a beam of electrons moving towards the sphere with the constant velocity v = 5 m/s and the concentration of electrons in the beam is ne = 3.2×1018 m3. How much charge per second is received by the sphere (find the current)? Assume that the electrons move fast enough.
