This statement is incorrect because Newton's third law works for objects at rest. Consider pulling on a string. Reason applies because there is a reaction pair for every action that acts on all forces. 

The law of universal gravitation is:

F\ =\frac{Gm_1m_2}{r^2}

Two masses attract each other.

Coulomb’s Law (Electricity):

F\ =\frac{kq_1q_2}{r^2}

Take two magnets and they repel (forces in opposite directions) or attract (forces in opposite directions) depending on their orientation. In both Cases, the third law is respected. For example: Gravity, electricity or magnetism etc. Newton’s third law therefore applies to all types of forces.
