The speed of electrons in a scanning electron microscope is 1 × 107 ms–1. If the protons having the same speed are used instead of electrons, then the resolving power of scanning proton microscope will be changed by a factor of:
(1) 1837
(2) \(\frac{1}{1837}\)
(3) \(\sqrt{1837}\)
(4) \(\frac{1}{\sqrt{1837}}\)
