Question

In the arrangement shown in the figure, all the surfaces are frictionless. The masses of the blocks are m1=20 kg and m2=30 kg. If F= 180 N, then the ratio of acceleration of mass m2 to that of m1 will be

Solution

FBD of the given diagram


We can see that block m2​ will remain stationary as there will not be any direct forces were acting, hence it's acceleration will be 0.
m1=20 kg
m2=30 kg
For m1:
T=m1am1
20am1=180
am1=9 m/s2
Therefore,
am2am1=0
Final Answer: 0
