Question

From the given set of charges, which charge (s) is/are not possible?
(a)3.2 x 10-20 C
(b) 6.4 x 10-18C
(c) 0.8 × 10-16 C
(d) 12.8 x 10-19 C
I know the answer but method to solve ....?​

Answer 1

Answer:

we know about the property of quantisation of charges....

• according to this method Q = ne where 'n' be any integers . so we should choose the given values of charges which can make the n an integer by deviding the charge of an one electron.here correct option is c) as here if we devide it by the charge of an one electron we can't find an integer.
