Answer 1

Answer:

Some forces in nature acts without in contact like gravitational forces they act from sun to earth where there is no - contact of interaction between sun and earth. Such, forces is known as Non - Contact forces

Answer 2

Answer:

Some force like magnetic force ,electrostatic force, and gravitational force, act on other bodies without any contact of surface. This property is called field force.

As far as magnetic force concern, the magnetic are surrounded by the magnetic lines of force which provide the magnetic attractive and repelling force .The same poles repel and the different poles attract.

The electrostatic force are exerted by the charged body on another charged or uncharged body .The charged body in use and opposite charge on the uncharged body and it get attracted by the body .here, the two bodies are at distance before the electrostatic force are exerted.

It is bordered in the earth attracts everybody even through they are at some distance .This force is called gravitational force or weight of the body. It various at different places.
