Question
In the figure, the blocks A, B and C of mass m each have acceleration a1, a2 and a3 respectively. F1 and F2 are external forces of magnitudes 2 mg and mg respectively .
Options
A.a1 = a2 = a3
B.a1 > a2 > a3
C.a1 = a2 , a2 > a3
D.a1 > a2 , a2 = a3
Solution
a1 =
a2 = 
a3 = 0a1 = g a2 =
So, a1 > a2 > a3
