A potential difference (p.d.) of 4800 V is applied between the cathode and anode of the tube. The cathode is heated and electrons are emitted from its surface. These electrons are then accelerated from rest and pass through a hole in the anode Cathode Anode Electrons 4800 V Show that the speed v of the electrons as they leave the anode is about 4 x 107 m s-1. V After leaving the anode, the electrons follow a parabolic path as...
