    220 N, 90 N
  • c)
     240 N, 96 N
  • d)
    260 N, 96 N
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
A body of mass 8 kg is hanging another body of mass 12 kg. The combina...
The tension T1 and T2 will be 240 N, 96 N.
Mass of the body = m1 = 12kg (Given)
Mass of the body = m2 = 8kg (Given)
Acceleration of the string - 2.2m/s² (Given)
Considering positive direction upwards -  
Thus,
T1− (m1+m2)g = (m1+m2)a
T1 = (m1+m2)g + (m1+m2)a
T1= (12+8)(2.2)+(12+8)(9.8)
T1 = 44 + 196
= 240 N
T2− (m2)g=(m2)a
T2=(m2)g+(m2)a
T2= (8)(2.2)+(8)(9.8)
T2 = 17.6 + 78.4  
= 96 N
