Question

According to Newton's 2nd law of motion correct equation is (where symbols have their usual meanings)

• A. $F=\frac{dp}{dt}$
• B. $F=ma$
• C. $F=v\frac{dm}{dt}$
• D. All of these

Answer 1

The correct option is B $F=ma$

$F=ma$ means that the force $F$ on an object is equal to the product of its mass $m$ and acceleration $a.$

the mathematical expression depicts newton's law of motion$.$

Hence,

option $\left(B\right)$ is correct answer.
