Two protons are separated by a distance of 1 nanometer. The magnitudes of gravitational, electromagnetic and strong nuclear forces between them are denoted by F_G , F_E and F_S respectively. Select the correct option.

Step-by-step solution

Distance between protons, r = 1 nm = 10⁻⁹ m. The strong nuclear force is a short-range force and is effective only up to distances of the order of 1 fm ( 10⁻¹⁵ m). At a distance of 1 nm, the strong nuclear force is practically zero. Thus, F_S 0 . The electromagnetic force between two protons is given by F_E = 1 4 ₀ e^2 r^2 . The gravitational force between two protons is given by F_G = G m_p^2 r^2 . The ratio of electromagnetic to gravitational force between two protons is independent of distance and is approximate
