An initially neutral conducting sphere has a radius R = 0.45 m. Electrons are fired towards the sphere with an initial speed of v = 4 × 106 m/s. Electrons striking the surface remain on the sphere and a net negative charge accumulates over time. Assume the electrons are fired far from the sphere. How many electrons will be deposited on the sphere before they no longer reach the surface?
