A subatomic particle could have a charge of
(1) 5.0 × 10–20 C (2) 8.0 × 10–20 C (3) 3.2 × 10–19 C (4) 5.0 × 10–19 C

Respuesta :

Answer:

(3) 3.2 × 10–19 C

Explanation:

The charge of a subatomic particle can only be an integer multiple of the fundamental charge, which is

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

So, let's analyze the 4 options:

(1) 5.0 × 10–20 C

[tex]\frac{5.0\cdot 10^{-20}C}{1.6\cdot 10^{-19} C}=0.31[/tex] --> not an integer number

(2) 8.0 × 10–20 C

[tex]\frac{8.0\cdot 10^{-20}C}{1.6\cdot 10^{-19} C}=0.5[/tex] --> not an integer number

(3) 3.2 × 10–19 C

[tex]\frac{3.2\cdot 10^{-19}C}{1.6\cdot 10^{-19} C}=2[/tex] --> integer number

(4) 5.0 × 10–19 C

[tex]\frac{5.0\cdot 10^{-19}C}{1.6\cdot 10^{-19}C}=3.13[/tex] --> not an integer number

So, the only option which is correct is (3).

Answer:

(1) 5.0 × 10–20 C (2) 8.0 × 10–20 C (3) 3.2 × 10–19 C (4) 5.0 × 10–19 C

Explanation:

3.2 × 10–19 C
