Asked by Fleur
An electron (m = 9 x 10-31 kg) leaves the cathode of a radio tube with zero initial velocity and travels in a straight line to the anode, which is 1 cm away. It reaches the anode with a velocity of 6 x 106 m s-1. If the force on the electron was constant, calculate:
the acceleration and the force
the time taken for the electron to reach the anode
the acceleration and the force
the time taken for the electron to reach the anode
