(ii) Weak nuclear force its strength is low and of the order of and short ranged. This force is responsible for radioactive decay.
(iii) Electromagnetic force act between the electrically charged particles. Its strength is of the order of . But its range is infinite.
(iv) Gravitational force is the force of attraction acting between two pieces of matter of the universe. Its strength is weak of the order of . But it's range is infinite.
