Question

A force produces an acceleration of $1{\text{m/s}}^2$ in a body of $3\text{kg}$. If the same force acts on a body of mass $1\text{kg}$, then what will be its acceleration?

• A. $1{\text{m/s}}^2$
• B. $2{\text{m/s}}^2$
• C. $3{\text{m/s}}^2$
• D. $4{\text{m/s}}^2$

Answer 1

The correct option is C $3{\text{m/s}}^2$

Magnitude of the force, $F=ma=3\times 1=3\text{N}$

Now, acceleration of $1\text{kg}$ body, $a=\frac{F}{m}=\frac{3}{1}=3{\text{m/s}}^2$
