A body of mass `m_(1)` exerts a force on another body of mass `m_(2)`. If the magnitude of acceleration of `m_(2)` is `a_(2)`, then the magnitude of the acceleration of `m_(1)` is ( considering only two bodies in space )

Options

A. Zero
B. `m_(2)a_(2)//m_(1)`
C. `m_(1)a_(2)//m_(2)`
D. `a_(2)`

Answer

B

Explanation

`F=m_(2)a_(2)=m_(1)a_(1)`
`therefore a_(1)=(m_(2))/(m_(1))a_(2)`
