Question

Gravitational force , weak force , electromagnetic force , nuclear force among this which is the strongest force

Answer 1

It, depends upon the intensity of the force applied:

But, If we take into consideration that all the magnitude are equal then:

Then Nuclear force would be the strongest as it's very hard to separate two things which connected by the action of nuclear charges.

Answer 2

Answer:

They are such forces which are exerted on objects by direct contact. The forces which acts on bodies when they are in actual contact are called the contact forces.

The following forces come under Contact Forces.

Frictional forces

Normal reaction force

Tension force as applied through strings

Force exerted by a spring

Force exerted during collision

Force exerted by a spring

Force exerted during collision

Force applied as a pull or push

Non Contact Force:

The forces which act on bodies without being physically touched, are called the non-contact forces.

The following forces come under non-contact forces :

Gravitational Force

Electrostatic Force

Magnetic Force

Hence, the odd man out is magnetic force.
