Question

How many electrons must be transferred to a body to produce a charge of 125 nc?

Answer 1

To produce a charge of 125 nC, approximately 7.81 x 10^18 electrons must be transferred to a body.

Step-by-step explanation:

To determine the number of electrons transferred to a body to produce a charge of 125 nC, we can use the formula: number of electrons (ne) = Total charge / charge per electron
Given that the charge per electron is -1.60 x 10^-19 C, we can calculate the number of electrons as follows: ne = 125 nC / -1.60 x 10^-19 C
Calculating this, we find that ne is approximately 7.81 x 10^18 electrons.

Answer 2

given:
charge to be produced =125 nc or 125*10^-9 c.
to find:
Number of electrons required to produce a charge of 125 nc.
solution:
the charge of an electron is 1.602 x 10^-19 C:
Then, number of electrons = 125 x 10^-9 / (1.602 x 10^-19)
= 78 x 10 ^ 10 electrons
so, 78 x 10^10 electrons must be transferred to a body to produce a charge of 125nc.
