Consider the system shown in figure. The pulley and the string are light and all the surfaces are frictionless. The tension in the string is (take g=10 ~m ~s ⁻² )
Options
- A0 ~N
- B1 ~N
- C2 ~N
- D5 ~N
Correct answer
D. 5 ~N
Step-by-step solution
If a is acceleration of m₂ , then from fig. From (i), m₂ g-T=m₂ a aligned & 1 g-m₁ a=m₂ a & 1 g= (m₁+m₂ ) a=(1+1) a & a= g 2 = 10 2 =5 ~m ~s ⁻² & T=m₁ a=1 5=5 ~N aligned
