Correct Answer: Option n
Explanation:
(a) Properties of cathode rays:
Cathode rays
are negatively charged.
travel in straight line in field free space.
are deflected by electric/magnetic field.
possess(kinetic) energy.
possess momentum.
(b)(i) The intensity of cathode rays may be increased by raising the temperature of the cathode/increasing the current through the heater.
(ii) The energy of cathode rays may be increased by raising the potential difference between the anode and the cathode/the anode potential.
