11. A body of mass ‘M’, at rest on a horizontal table, the body remains at rest. What forces are acting on an object at rest

Friction

Gravitational Pull

Normal Reaction

** B & C**

12. A body of mass 15 kg moving with a velocity of 10 m/s has its velocity reduced to 6 m/s in two seconds. The force that required to this change in velocity is

60 N

20 N

13. Newton’s first law states that

**A body continues to be in a state of rest or of uniform motion in a straight line unless it is acted upon by a net external force**

The rate of change of momentum of a body is directly proportional to the net force acting on the body

To every action, there is an equal and opposite reaction

The product of mass m of a body and its velocity v

14. Newton’s second law states that

A body continues to be in a state of rest or of uniform motion in a straight line unless it is acted upon by a net external force

** The rate of change of momentum of a body is directly proportional to the net force acting on the body**

To every action, there is an equal and opposite reaction

The product of mass m of a body and its velocity v

15. Newton’s third law states that

A body continues to be in a state of rest or of uniform motion in a straight line unless it is acted upon by a net external force

The rate of change of momentum of a body is directly proportional to the net force acting on the body

** To every action, there is an equal and opposite reaction**

The product of mass m of a body and its velocity v

16. Linear momentum p is defined as

To every action, there is an equal and opposite reaction

**The product of mass m of a body and its velocity v**

17. First law of Motion is also known as

Law of Equilibrium

** Law of Inertia**

Law of Momentum

None of these

18. Three laws of Motion is given by
