Question

The value of charge on the oil droplets experimentally observed were -1.6×10^-19 and -4×10^-19 coulomb.The value of the electronic charge, indicated by these results is​

Answer 1

Answer:

The answer is -2.

Explanation:

We know that:

1 electronic charge = 1.6××10-19

The value of charge on oil droplets is = -1.6××10-19

So, the value of the electronic charge is -1.

The value of charge on oil droplets is =  -4××10-19

So, the value of the electronic charge is −4×10−19/1.6×10−19 = 2.5

The electronic charge is an integer, so it is -2.

Thus the value of the electronic charge is -2.
