Select the correct alternative :
- a)The charge gained by the uncharged body from a charged body due to conduction is equal to half of the total charge initially present.
- b)The magnitude of charge increases with the increase in velocity of charge
- c)Charge can not exist without matter although matter can exist without charge
- d)Between two non-magnetic substances repulsion is the true test of electrification (electrification means body has net charge)
Correct answer is option 'C,D'. Can you explain this answer?

A.Statement A is wrong.
B.m= m0/√(1− v2/c2)
specific charge q/m=q/m0√(1−(v2/C2))
so, as v increases the specific charge decreases
C. None of the fundamental particles that form the Standard Model have charge without mass. The Standard Model describes all energy and matter that makes up the universe, except gravitation. And gravitation does not have charge, it has mass.
D.Yes. Repulsion is observed only when two bodies have like charges that means the bodies must be charged. Therefore, repulsion is sure test for electrification than attraction.

Select the correct alternative :a)The charge gained by the uncharged b...
Explanation:
Option C is correct because charge is a property of matter. It is the result of an imbalance of protons and electrons in an atom or molecule. Therefore, charge cannot exist without matter.
Option D is correct because if two substances are non-magnetic, the only interaction between them is electrostatic. If they repel each other, it means that they have the same type of charge (either both positive or both negative), which is a sign of electrification.
To summarize:
Charge is a property of matter and cannot exist without it. Electrification can be detected by repulsion between two non-magnetic substances.
