How does charging by conduction compare with charging by induction? a charged object is needed in conduction but not in induction. two neutral objects are needed in conduction but not in induction. objects must touch in induction but not in conduction. oppositely charged objects form in induction but not in conduction.

Oppositely charged objects form in induction but not in conduction.

Explanation:

in induction phenomenon the charged object is placed near a neutral conductor. then due to electric field of the charged object the neutral conductor will have charge separation in it. Here opposite charge come near the surface which is known as induction

While in conduction phenomenon the neutral object is made contact with the charged body due to which the charge is transferred to the neutral object

here the same charge will occur in the neutral object as that of charge body is having on it

so here correct answer will be

Oppositely charged objects form in induction but not in conduction.

the answer is b, have negligible mass
