Question

Which of the following charge is possible :
A. 10.2×10*-19C
B.11.2×10*-19C

Answer 1

Answer:

Only the option B) 11.2 × $10^{-19}$ C

Explanation:

11.2 × $10^{-19}$ C is equal to charge on 7 electrons.

But when you talk about 10.2 × $10^{-19}$ C, it lies between charge on 6 and 7 electrons, which isn't possible.
