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 naturally occurring electrons is removed. The radius of the orbit is2.04 × 10-11 m.
Part A: Determine the magnitude of the electron's centripetal acceleration.
I need help to solve the above problem and provide some pertinent background for this problem.
A marble is thrown horizontally with a speed of 16 m/s from the top of a building. When it strikes theground, the marble has a velocity that makes an angle 47° with the horizontal. From what height above the ground was the marble thrown?
