Two bodies of masses 4 kg and 5kg are acted upon by the same force. If the acceleration of lighter body is `2m//sec^(2)`, then the acceleration of the heavier body is:-

Options

A. `4.2 m//s^(2)`
B. `3.6 m//s^(2)`
C. `2.4 m//s^(2)`
D. `1.6 m//s^(2)`

Answer

D

Explanation

`a_(1)=(m_(2))/(m_(1))a_(2)=(4)/(5)xx2=1.6m//s^(2)`
