Question

answer both the questions​

Answer 1

A. b) 2 and 3

ExPlanation;

See, when ever two balanced forces are acting on a body there will be no change in its state or motion, why? because both of the forces are equal and in magnitude and it makes the system an equlibrium. However, there will be change in its shape and size. Let's understand this by using an example, suppose I'm pulling a book and the same book is pulled by you, now the force exerted by both of us is equal in magnitude and thus the book will remain at its place however,due to force there will be change in its shape.

B. c) Newton's third law of motion

ExPlanation;

According to newton's third law of motion, every action has an equal and opposite reaction. So, when we fired using the cannon, we exerted a force in the forward direction and as the cannon is exerting some force it will also experience a force which is equal in magnitude but opposite in direction.
