Question
A force produces an acceleration of 4 ms-2 in a body of mass m1 and the same force produces an acceleration of 6 ms-2 in another body of mass m2. If the same force is applied to (m1 + m2), then the acceleration will be:
Options
A.10 ms-2
B.2 ms-2
C.2.4 ms-2
D.5.4 ms-2
Solution
F = m1 4 [Newton′s II law for m1]
F = m2 6 [Newton′s II law for m2]
F = (m1 + m2)a [Newton′s II law for (m1 + m2)]
⇒ F =
⇒ 1 = 
⇒ a = 2.4 m/s2.Create a free account to view solution
