Hello students in this question we have to identify an incorrect statement.
00:05
Okay, so moving to the first statement which says that cathode rays are positive cathode rays are positive charged particles.
00:15
So this is a wrong statement.
00:17
So we find that our answer is a okay now checking another option.
00:22
So option b it is saying that cathode rays have momentum and then cathode rays have momentum, p and energy.
00:32
So since it is a negatively charged particle, so a particle will have a mass.
00:37
So if mass is given, then if it is moving, then it will have a momentum and it also may have energy.
00:45
So if particle is given, then it may have photon as a momentum as well as energy.
00:51
So this is correct option.

Now statement...
