Question

. How many electrons should be removed from a
conductor so that it acquires a positive charge of 3.5×10 to the power -9 c?????
pls give full explaination of answer​

Answer 1

Q = ne

here Q= 3.5nC = 3.5 x 10-6 C

e = 1.6 x 10-19 C

so 

 3.5 x 10-6  = n x 1.6 x 10-19 

n = 3.5 x 10-6 / 1.6 x 10-19 

n = 2.1875 x 1019

so 2.1875 x 1019 electrons should be removed to acquire a positive charge of 3.5nC

Plz mark as brain list.

Answer 2

Answer:

1 coulomb is equal to 6.42 quintillion electrons. That's 6420000000000000000 electrons (6.42 X 10^18)

When that many electrons flow through a conductor it is labelled 1 amp of current.
