Problem: Suppose a single electron orbits about a nucleus containing two protons (+2e), as would be the case for a helium atom from which one of the two naturally occurring electrons is removed. The radius of the orbit is 2.65 x 10-11 m.
Part A: Determine the magnitude of the electron's centripetal acceleration.
Please explain each step and equations used to find the magnitude of the electron's centripetal acceleration.
