The charge of how many negatively charged particles would be equal to 100 µC. Assume the charge on one negative particle is 1.6 𝐱 10⁻¹⁹ C ? Ans. (6.25 𝐱 10¹⁴ )


Given Data:


Total Charge = Q = 100 µC = 100 𝐱 10⁻⁶ C 
(∴ µ = 10⁻⁶)

Charge on electron = e  = 1.6 𝐱 10⁻¹⁹ C


To Find:


Numbers of negatively charged particles = n = ? 



Solution:


We have the formula

Q = ne 

or

n = `\frac{Q}{e}`

by putting the values

n = `\frac{100 𝐱 10⁻⁶ C}{1.6 ｘ 10⁻¹⁹ C}` 

n = 62.5 𝐱 10⁻⁶⁺¹⁹ 

n = 62.5 𝐱 10¹⁵ 

or

n = 6.25 𝐱 10¹⁶  ---------------Ans.

The numbers of negatively charged particles are 6.25 𝐱 10¹⁶
