The minimum value of charge on any charged body may be (a) 1.6 × 10^-19 (b) 1 coulomb (c) 1μC (d) 4.8 × 10^-12 coulomb

Question:

The minimum value of charge on any charged body may be 

(a) 1.6 × 10^-19 

(b) 1 coulomb 

(c) 1μC 

(d) 4.8 × 10^-12 coulomb

Answer:

Correct option: (a) 1.6 × 10^-19

Explanation:

The charge of any charged body in this universe is always a multiple of the charge of an electron. So the minimum charge of a body is ±e ( where e≈ 1.602×10^-19 Coulomb). If charge of a body is Q then Q= ±ne, where n is an integer.

Hence, the correct answer is option (a) "1.6×10^-19".
