Homework Statement

Homework Equations

magnitude of the force is k(e^2)/(r^2)
k = 9 * 10^9 N*m^2/C^2
e = 1.6 * 10^-19C

The Attempt at a Solution

ke^2/(r^2) = (9*10^9 N * m^2/C^2)(1.6*10^-19C)^2/(.39^2 + .40^2)*10^-18m^2 = 7.38 *10^-10 N

ok this is what I got resultant y is y/sqrt(a^2+y^2)

then resultant x is x/sqrt(a^2+y^2)

this is what was stated in the book

Did you get a numerical answer?

The electric force on the proton can be calculated using Coulomb's Law, which states that the magnitude of the force between two charged particles is equal to the product of their charges divided by the square of the distance between them, multiplied by a constant. In this case, the charged particles are a proton and another charged object, and the constant is known as the Coulomb constant (k). Using the given values for the charge of a proton (e) and the distance between the particles (r), we can plug these values into the equation and calculate the magnitude of the force. The resulting value is 7.38 * 10^-10 Newtons, which represents the electric force on the proton.
