Q.
A certain force gives an object of mass m2 an acceleration of 12m/s2 and an object of mass m2 an acceleration of 3m/s2. What acceleration would the force give to an object of mass m2=m1 ?
If force applied on mass m1, then acceleration ⇒12=m2F
If force applied on mass m2, then acceleration 3=m2F
When same force is applied on m2−m1 Then,
acceleration a=m2−m1F=3F−12FF =4m/s2
