Question

If an object is charged by contact, it will acquire:
a. Opposite charge
b. Negative charge always
c. Same charge as the charged body
d. Positive charge always

Answer 1

Hint: An object can be charged by rubbing and by induction. When two bodies are charged by the process of rubbing, they acquire equal and opposite charges.

Complete step by step answer:
> Option A says about the opposite charges but when an object is charged by contact there is a transfer of charges from the charged body to the charged free body with no change in the sign of the charges.

> Option B says about the negative charges but when an object is charged by contact there is a transfer of charges from the charged body to the charged free body with no change in the sign of the charges.

> Option C says about the same charges, when an object is charged by contact there is a transfer of charges from the charged body to the charged free body with no change in the sign of the charges.

> Option D says about the equal and opposite charges but when an object is charged by contact there is a transfer of charges from the charged body to the charged free body with no change in the sign of the charges and it may be equal or may not be.

Hence, the correct answer is option (C).

Note:
• A neutral body can be charged by bringing it in close contact with a charged body and the neutral body gets charged.
• Same charged bodies repel each other.
• Conduction involves the contact of a neutral object to a charged object from the charged particle.
• Being contacted from the charged aluminum plate as the result becomes charged due to the neutral metal sphere.
• Oppositely charged bodies attract each other.
• Electrons, protons, neutrons compose an atom.
