How Does a Proton's Speed Affect Coulombic Impulse on an Electron?

[ericwithakay]

Homework Statement

A high-speed proton of electric charge e is modeled as moving with constant
speed v past an electron of mass m and charge −e initially at rest. The electron is a distance α from the straight-line path of the proton and we assume it ‘scarcely moves’ while the proton comes and goes. Use the standard Coulomb Force law to find the components of the net impulse delivered to the photon.

Homework Equations

F= (-Ke^2)/(r^2)

The Attempt at a Solution

I'm not sure how to start this one.

I think we need to solve for the components of force, and then use that to solve for net impulse but I'm not sure how to go about this.
