A force F applied to an object of mass m...

A force F applied to an object of mass `m_(1)` produces an acceleration of `3.00m//s^(2).` The same force applied to a second object of mass `m_(2)` produces an acceleration of `1.00m//s^(2).`
(i) What is the value of the ratio `m_(1)//m_(2)` ?
(ii) If `m_(1) and m_(2)` are combined, find their acceleration under the action of the force F.

Text Solution

Verified by Experts

The correct Answer is:
`(1)(m_(1))/(m_(2))=1/3(ii) a=3//4m//s^(2)`
