Answer
d.Explanation
- Particles are negatively charged. Charge of - particle is -1 and the mass of the particle is th of the proton.
particles are fast and light
They have medium penetration power.
Ionize other atoms not strong as Rays.
-rays are not particles they are waves or rays and they do not have mass and charge. And these rays have high penetration power.

Question 149
Question
MCQ▾In the circuit, what is the current in the lower branch?
Choices
Choice (4) | |
---|---|
