Answer:

+3.2 10-18 C

Explanation:

The net electric charge on an object is determined by the number of protons or electrons on the object, therefore it must be an integer multiple of the proton/electron charge, whose value is

[tex]e=1.6 \cdot 10^{-19} C[/tex]

So, let's analyze each option provided:

-1.8 10-18 C --> not an integer multiple of the fundamental charge

-0.80 10-19 C --> not an integer multiple of the fundamental charge

+2.4 10-19 C --> not an integer multiple of the fundamental charge

+3.2 10-18 C --> this is an integer multiple of the fundamental charge: in fact, we have

[tex]\frac{+3.2\cdot 10^{-18} C}{+1.6\cdot 10^{-19}C}=20[/tex]

So, the last option is the correct answer.

The net charge that can be found on any object from the options is; D: +3.2 × 10^(-18) C

The formula for the charge on an electron is;

q = 1.6 × 10^(-19) C

Now, any net charge from the options will have to be a positive integer multiple of this charge on an electron.

  • A) -1.8 × 10^(-18) C;

Let's check by dividing by the charge on an electron to get;

(-1.8 × 10^(-18))/(1.6 × 10^(-19)) = -9.473

  • B) -0.8 × 10^(-19) C;

Let's check by dividing by the charge on an electron to get;

(-0.8 × 10^(-19))/(1.6 × 10^(-19)) = -0.5

  • C) 2.4 × 10^(-19) C;

Let's check by dividing by the charge on an electron to get;

(2.4 × 10^(-19))/(1.6 × 10^(-19)) = 1.5

  • D) 3.2 × 10^(-18) C;

Let's check by dividing by the charge on an electron to get;

(3.2 × 10^(-18))/(1.6 × 10^(-19)) = 20

The only one that has a positive integer as a factor is D) 3.2 × 10^(-18) C;
