Question

an object with net positive charge 2×10^-12C contains 1.5×10^7 protons find no of electrons​

Answer 1

Answer:

Explanation:

One coulomb is the fundamental SI unit of charge. It is defined as the charge in one Ampere of current passed for one second.

Now for an electron, the amount of charge it carries is 1.6*10^-19 C.

So for making a charge of 1 Coulomb, the number of electrons required will be:

Q = n*e

Q = 1 C and e = 1.6*10^-19

n = 1/(1.6*10^-19)

n = 6.25*10^18 number of electrons

Answer 2

Explanation:

for making a charge of 1 c . the number of electrons required will be:-
