MCQ
Induction occurs due to $........$?
- ✓Movement of electron.
- BLeakage of charge.
- CIonization of atoms.
- DUniform charge distribution.
✓
Answer
Correct option: A.
Movement of electron.
When a positive or negative charged body comes close to another body, the electrons of the second body redistribute themselves. Electrons of the second body are attracted by the positively charged body and repelled by the negatively charged body.
