Question

State True or false
1. Pascal is the unit of force. :
2. Force applied on an object in opposite directions add to one another. :
3. A force can act on an object with or without being in contact with it. :
4. Force of gravity is a contact force. :
5. If the area over which the force acts decreases, the pressure increases

Answer 1

Answer:

1. It is false because unit of force is Newton.

2.Forces applied on an object in the same direction add to one another. If the two forces act in the opposite directions on an object, the net force acting on it is the difference between the two forces.So the statement is true.

3.Magnetic force is the force which can act on an object without making any contact with the objects. Example: Force exerted by a magnet on another magnet.So the statement is true.

4.It is false because gravitational force is an example of non contact force.

5.If the area over the force acts decreases, the pressure increases because force and pressure are inversely propositional to each other.So the statement is true.

I hope this helps u!!!! ^_^
