A body of mass 8 kg is hanging from another body of mass 12 kg. The combination is being pulled by a string with an acceleration of 2.2 ms-2. The tension T1 and T2 will be respectively: (use g = 9.8m/s2)

200 N, 80 N
220 N, 90 N
240 N, 96 N
260 N, 96 N

Solution:

Taking both the objects as one system

T1- 20g=20a ⇒ T1= 20(g+a)=20*12= 240 N

Now taking lower object as a different system

T2-8g=8a ⇒T2=8(g+a)=8*12= 96N
