Question

A body A of mass m1 exerts a force on another body B of mass m2. If the acceleration of B be a2, then the acceleration (in magnitude) of A is (A) (m2/m1)a2 (B) m1m2a2 (C) (m1/m2)a2 (D) (m1+m2)a2

Tardigrade Admin · Accepted Answer

Force on B=m2a2 ∴ Force on A=m1a1 Acceleration of A=(m2a2/m1)

Q. 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

$\frac{m _{2}}{m _{1}} a_{2}$

$m_{1} m_{2} a_{2}$

$\frac{m _{1}}{m _{2}} a_{2}$

$(m_{1} + m_{2}) a_{2}$

Force on $B = m_{2} a_{2}$

$∴$ Force on $A = m_{1} a_{1}$

Acceleration of $A = \frac{m _{2} a _{2}}{m _{1}}$

Q. A body A of mass m1​ exerts a force on another body B of mass m2​. If the acceleration of B be a2​, then the acceleration (in magnitude) of A is

m1​m2​​a2​

m1​m2​a2​

m2​m1​​a2​

(m1​+m2​)a2​
