Question

the charge on an oil drop is calculated to be 6.25*10-19 coulomb.the number of excess electrons on the drop is?​

Answer 1

Answer:

Explanation:

I don't know really sorry

Answer 2

Answer:

the number of electrons in the drop is 4.

Explanation:

The charge on one electron is 1.60×10

−19

C.

From the formula q=n×e,

The number of electrons n=

1.60×10

−19

6.39×10

−19

=4.

Hence, the number of electrons in the drop is 4.
