PHYSICS [2 Mark Question Answer]

Total forces acting downwards = 2N + 22N = 24 N Total forces acting upwards = 8N + 14N = 22N Resultant force = Difference between the magnitude of forces = 24N – 22N = 2N The wooden block will move in the downward direction with the resultant force of 2N acting on it.

Agent exerting the force is the child himself (muscle of the child).
The object on which the force is acting is the child himself. The force is moving the child from a stationaiy object.

Agent exerting the force is human fingers. The object on which the force is acting is the medicinal tube. The force is changing the shape of the tube and moving the oinment out of the tube.

Agent exerting the force can be a machine (electric power) or human. The object on which the force is acting is the orange. The force is moving the orange md changing the shape of it.

Magnetic force comes into play even when the magnet and other object (like iron) are kept at a distance and not in direct contact with each other. Hence, magnetic-force is considered as an action-at-a-distance force.

A force exerted by a surface to support the weight of a body in contact with it is called normal force. It is always perpendicular (right angles) to the surface. For example, when a book is kept on a table, the table exerts a normal force which acts upward on the book to support its weight.
