Question (2.5) Answer :
Contact forces acts when objects are in physical contact.Contact may be continuous or impulsive.
While Non-contact forces acts when there is no physical contact in objects.
Gravitational force : Non-Contact Force
Friction : Contact Force
Normal force : Contact Force
Magnetic force : Non-Contact Force
Spring force : Contact Force
Tension : Contact Force

Whenever you face a problem involving forces, always start with a free-body diagram.
Learning Goal: To gain practice drawing free-body diagramsWhenever you face a problem involving forces, always start with a free-body diagram.To draw a free-body diagram use the following steps:Isolate the object of interest. It is customary to represent the object of interest as a point in your diagram.Identify all the forces acting on the object and their directions. Do not include forces acting on other objects in the problem. Also, do not include quantities, such as velocities and accelerations, that do...

(b (b d o р There are several forces acting on each sphere: gravity is pulling it down, the electric field is pushing it away from the other sphere, and the tension on the string is keeping it aloft. The spheres are not accelerating, which means that the forces are in equilibrium.
