Principle of conservation of linear momentum is deduced from
a. Newton's 1st law
b. Newton's 2nd law
c. Newton's 3rd law
d. None of above

Dear Student,

Newtons 2nd law states that , rate of change of linear momentum is directly proportional to the force acting on the body.

Therefore, if No external force acts on a body, it's linear momentum will remain as a constant.

Hence principle of conservation of linear momentum is deduced from  Newton's 2nd law.

Ans : b. Newton's 2nd law
