A protein molecule in an electrophoresis gel has a negative charge.The exact charge depends on the pH of the solution, but 30 excesselectrons is typical. What is the magnitude of the electric forceon a protein with this charge in a 1500 N/C electric field?

Answer :

Answer:

The magnitude of the electric force on a protein with this charge is [tex]7.2\times10^{-15}\ N[/tex]

Explanation:

Given that,

Electric field = 1500 N/C

Charge = 30 e

We need to calculate the magnitude of the electric force on a protein with this charge

Using formula of electrostatic force

[tex]F=Eq[/tex]

Where, F = force

E = electric field

q = charge

Put the value into the formula

[tex]F=1500\times30\times1.6\times10^{-19}[/tex]

[tex]F=7.2\times10^{-15}\ N[/tex]

Hence, The magnitude of the electric force on a protein with this charge is [tex]7.2\times10^{-15}\ N[/tex]
