a)Contact force occurs due to the contact between two different objects. Non-contact force occurs due to either attraction or repulsion between two objects such that there is no contact between these objects. There is no field linked with the contact force. There is always a field linked with non-contact force.
b)Balanced forces: When a number of forces acting on a body do not cause any change in its state of rest or of uniform motion along a straight line then the forces are said to be balanced forces. In other words, a body is said to be underbalanced forced when the resulting force acting on the body is zero.
The balanced forces:
⋅ Cannot set any stationary body into motion.
⋅ May change the shape and size of soft objects.
⋅ Cannot change the speed/velocity of a moving body.
Unbalanced forces:
When the resultant of all the forces acting on a body is not zero, then forces are called unbalanced forces.
Answers & Comments
Answer:
The force which act on only contact is called contact force like Muscular force Normal force etc.
Non contact force act not with the contact like gravitational force
Balanced force is force which applied on a balance manner like 10N from North And south both to balance the force
Non balance is not balance like 10 Joules from North and 15 Joules from South
