Given that the charge on an electron is -1.6 x 10^-19 Coulombs, what is the magnitude of the electric force on an electron in Newtons when it is placed in an electric field of strength 12,000 Volts/m? A)1.6 x 10^-19 B)3.2 x 10^-19 C)1.92 x 10^-15 D)6.4 x 10^-19 E)4.5 x 10^22

Respuesta :

Given,

The charge on an electron is

[tex]q=-1.6\times10^{-19}\text{ C}[/tex]

The electric field strength is

[tex]E\text{ = 12,000 Volts/m}[/tex]

Solution:

The electric force is calculated by the formula,

[tex]F=qE[/tex]

Put the given values in the formula.

[tex]\begin{gathered} F=(1.6\times10^{-19}\text{ C\rparen}\times(12,000\text{ Volts/m\rparen} \\ F=19.2\times10^{-16}\text{ N} \\ F=1.92\times10^{-15}\text{ N} \end{gathered}[/tex]

Thus, the given options c is correct.
