A system containing masses and pulleys connected on an inclined plane is shown in the figure. If the system is in equilibrium then the value of (m ) is
Options
- A(1 ~kg )
- B(0.5 ~kg )
- C(0.75 ~kg )
- D(0.25 ~kg )
Correct answer
B. (0.5 ~kg )
Step-by-step solution
According to the question, the complete situation is shown in the following figure, Since, system is in equilibrium, hence ( aligned T & =m g (i) T & = (2 g-T₁ ) 30^ (ii) T₁ & =1 g (iii) aligned ) ( ) From Eqs. (ii) and (iii), we get ( aligned & T=(2 g- l g) 30^ =g 30^ & T= g 2 (iv) aligned ) ( ) From Eqs. (i) and (iv), we get, ( aligned m g & = g 2 m & =0.5 ~kg aligned )
