A proton is at the origin and an electron is at the point x = 0.37 nm, y = 0.39 nm Find the electric force on the proton?

I don't even know where to start. Can someone help me?

Find the distance to the point from the origin.

d=sqrt (x^2+y^2) working it in meters

Then coulombs law.

Of course! I can help you with that.

To find the electric force on the proton, we can use Coulomb's law, which states that the electric force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

Coulomb's law formula is given by:
F = (k * q1 * q2) / r^2

Where:
F is the electric force,
k is Coulomb's constant (8.99 x 10^9 N m^2/C^2),
q1 and q2 are the charges of the particles,
and r is the distance between the particles.

In this case, the proton and the electron have opposite charges, so we will consider the charge of the proton as +e (1.6 x 10^-19 C) and the charge of the electron as -e (-1.6 x 10^-19 C).

The distance between them can be calculated using the Pythagorean theorem since we have the x and y coordinates of the electron.
Using the given values: x = 0.37 nm and y = 0.39 nm,
we can calculate r using the formula: r = sqrt(x^2 + y^2).

Now we can substitute the values into Coulomb's law formula and calculate the electric force on the proton.

F = (k * q1 * q2) / r^2
= (8.99 x 10^9 N m^2/C^2) * (1.6 x 10^-19 C) * (-1.6 x 10^-19 C) / (r^2)

I hope this helps you understand how to approach the problem. Let me know if you need any further assistance!
