Question

1 State whether the contact force or non–contact force is responsible in the following

incidents.

4) Nayana lifts a bucket full of water.​

Answer 1

Explanation:

It is not necessary for the two objects to be in contact (touch) with each other to exert gravitation force, magnetic force and electric force. These three forces can be exerted even if the two objects are separated by a finite distance. Thus these forces are non-contact forces.
