#### Question

Two protons are kept at a separation of 10 nm. Let F_{n} and F_{e} be the nuclear force and the electromagnetic force between them.

F

_{e}= F_{n}F

_{e}>> F_{n}F

_{e}<< F_{n}F

_{e}and F_{n}differ only slightly.

#### Solution

F_{e} >> F_{n}

Two protons exert strong attractive nuclear force and repulsive electrostatic force on each other. Nuclear forces are short range forces existing in the range of a few fms. Therefore, at a separation of 10 nm, the electromagnetic force is greater than the nuclear force, i.e. F_{e} >> F_{n}.

Is there an error in this question or solution?
