is removed from o.1 % atom, what will be the charge on
the sphere?​

Answer 1

Answer:

ANSWER

Given,  

n=4×10  

23

×0.1%

n=4×10  

23

×  

100

0.1

​  

=4×10  

20

 

e=1.6×10  

−19

C

The charge is quantised, q=ne

q=4×10  

20

×1.6×10  

−19

=64C

The electron is negative charge particle.

So,q=−64C
