A proton is at the origin and an electron is at the point x = 0.36nm , y= 0.30nm .

What is your question?

If they want the elecrical force, use Coulomb's Law. It will an attraction force along the line connecting the two particles

To determine the distance between the proton at the origin and the electron at the given point, you can use the distance formula in two dimensions. The distance formula is derived from the Pythagorean theorem and is defined as:

Distance = √((x2 - x1)^2 + (y2 - y1)^2)

In this case, since the proton is at the origin (0, 0), the coordinates of the proton are (x1, y1) = (0, 0). The coordinates of the electron are (x2, y2) = (0.36nm, 0.30nm).

Now, plug in the values into the distance formula:

Distance = √((0.36nm - 0)^2 + (0.30nm - 0)^2)

Simplifying:

Distance = √((0.36nm)^2 + (0.30nm)^2)

Now, calculate the values inside the square root:

Distance = √((0.36nm)^2 + (0.30nm)^2)
= √(0.1296nm^2 + 0.09nm^2)
= √(0.2196nm^2)
= 0.468nm

Therefore, the distance between the proton at the origin and the electron at the given point is approximately 0.468nm.
