Which of the following is the weakest force?

Solution
The correct option is B Gravitational force
Answer is B.
Gravity is a very, very weak force. In a hydrogen molecule it pulls the two protons together with a force about 36 powers of ten weaker than the electric force between them.
Therefore, on small scales (within an atom/molecule), the other forces are much stronger, but on larger scales, it seems that gravity is a far stronger force; e.g. planets are held to the sun by gravity.
Hence, among the given options, gravitational force is the weakest.
