Which of the following represents fundamental force of nature ?


A) Gravitational force, Coulomb's force : strong surface tension force; weak van der Waal's force

B) Gravitational force; electromagnetic force; strong viscous force; weak nuclear force

C) Gravitational force; magnetostatic force; strong nuclear force; weak frictional force

D) Gravitational force; electromagnetic force; strong nuclear force; Weak nuclear force

Answer:

Option D

Explanation:

There are four types of fundamental  forces in nature namely, (i) Gravitational force (ii) electromagnetic force (iii) strong nuvlear force and (iv) weak nuclear forces

However , other forces like , strong surface tension , weak van der waal's  force, viscous force, etc are the forces which can be derived from these fundamental forces.
