Cathode rays are streams of electrons observed in vacuum tubes. To determine their properties, let’s break down the options:
Mass only: This is not correct because cathode rays have both mass and charge.
Charge only: This is also incorrect because while cathode rays do have a charge (negative), they also have mass.
No mass and no charge: This is incorrect as well. Cathode rays do have both mass and charge.
Both mass and charge: This is the correct answer. Cathode rays consist of electrons, which have a negative charge and a very small mass.
So, the correct answer is D. both mass and charge.
