Three blocks of masses 2 ~kg , 3 ~kg and 5 kg are connected to each other with light string and are then placed on a frictionless surface as shown in the figure. The system is pulled by a force F=10 ~N , then tension T₁ is

Options

  1. A1 N
  2. B5 N
  3. C8 N
  4. D10 N

Correct answer

C. 8 N

Step-by-step solution

Acceleration of the system aligned a & = F m = 10 2+3+5 & = 10 10 =1 ~m / s ^2 T₁ & =(3+5) a=8 1=8 ~N aligned
