Question

Calculate the acceleration produced in a body of mass $50g$ when acted upon by a force of $20N$.

• A. $0.4m{s}^{-2}$
• B. $4m{s}^{-2}$
• C. $400m{s}^{-2}$
• D. $2.5m{s}^{-2}$

Answer 1

The correct option is C $400m{s}^{-2}$

We know that force is nothing but the product of mass and acceleration that is $F=m\times a$.

In this we have $F=20N;m=50gram$, that is $m=50/1000Kg$. Acceleration that is $a=20\times 1000/50$. Hence acceleration is equal to $400m/s^2$.
