If an object has a net positive charge of 4.0 coulombs, the object possesses (1) 6.3 × 10^18 more electrons than protons (2) 2.5 × 10^19 more electrons than protons (3) 6.3 × 10^18 more protons than electrons (4) 2.5 × 10^19 more protons than electrons

Answer :

Answer:

(4) [tex]2.5 \times 10^{19}[/tex] more protons than electrons

Explanation:

Total positive change on the object is given as

[tex]Q = 4 C[/tex]

now by the law of quantization of charge we know that the charge on any body is always in form of integral multiple of charge of an electron.

So we will have

[tex]Q = N e[/tex]

here we know that

[tex]4 = N(1.6 \times 10^{-19})[/tex]

[tex]N = 2.5 \times 10^{19}[/tex]

Now we know that the object is positively charged so here electrons must be less in numbers than protons

so correct answer will be

(4) [tex]2.5 \times 10^{19}[/tex] more protons than electrons
