If we assume that an electron is orbiting a proton just like the moon orbits the Earth, find the electron's orbital speed due to the gravitational attraction between itself and the proton. Take the orbital radius as 1.00 x 10⁻¹⁰ m (This is a very wrong assumption to make.)
a. 1.11 x 10⁻²⁷ m/s
b. 3.33 x 10⁻¹⁴ m/s
c. 1.06 x 10⁻²⁷ m/s
d. 1 11x10⁻¹³ m/s
