Question

Which of the Newton’s law explains difficulty for a fireman to hold a hose pipe, which ejects large amounts of water at high velocity.

• A. Newton’s First law
• B. Newton’s Second law
• C. Newton’s Third law
• D. $E=m{c}^2$

Answer 1

The correct option is C Newton’s Third law

The ejection of large amount of water at high velocity from a hose pipe results in development of an equal and opposite force of reaction on the hose pipe by the water jet in the backward direction, that is why it becomes difficult for the fireman to hold the hose pipe.
