Question

All free electric charges can be
($e=$ single unit of charge i.e. the magnitude of charge on electron )

• A. odd multiples of $e$
• B. fractional multiples of $e$
• C. even multiples of $e$
• D. negative multiples of $e$

Answer 1

Answer: (A), (C), (D)

The correct options are
A odd multiples of $e$
C even multiples of $e$
D negative multiples of $e$

Charges are acquired by either gain or loss of electrons .

And electron transfer can occur only in form of integers, fraction of electron can't be shared.

Hence, charge on a body can be positive or negative integral multiple of $e$.

Answer-(A),(C),(D)
