Compute each part of given problem:
Problem: A 150MW laser pulse is focused with a lens to a diameter of 2.0m.
Part A: What is the laser beams electric field amplitude at the focal point?
Part B: What is the ratio of the laser beams electric field to the electric field that keeps the electron bound to the proton of a hydrogen atom? The radius of the electron's orbit is 0.053 nm.
Any expert will able to provide correct answer for the above problem.
