Question

A body A of mass $m_{1}$ exerts a force on another body B of mass $m_{2}$. If the acceleration of $B$ be $a_{2}$, then the acceleration (in magnitude) of $A$ is

• A. $\frac{m_{2}}{m_{1}}a_{2}$
• B. $m_{1}m_{2}a_{2}$
• C. $\frac{m_{1}}{m_{2}}a_{2}$
• D. $(m_{1}+m_{2})a_{2}$

Answer 1

Answer: (A)

Force on $B=m_{2}a_{2}$
$\therefore $ Force on $A=m_{1}a_{1}$
Acceleration of $A=\frac{m_{2}a_{2}}{m_{1}}$
