A body of mass m is suspended by two strings making angles ₁ and ₂ with the horizontal ceiling with tensions T₁ and T₂ simultaneously. T₁ and T₂ are related by T₁= 3 T₂ . the angles ₁ and ₂ are
Options
- A₁=30^ ₂=60^ with T ₂= 3 mg 4
- B₁=60^ ₂=30^ with T ₂= mg 2
- C₁=45^ ₂=45^ with T ₂= 3 mg 4
- D₁=30^ ₂=60^ with T ₂= 4 mg 5
Correct answer
B. ₁=60^ ₂=30^ with T ₂= mg 2
Step-by-step solution
aligned & T ₁ ₁+ T ₂ ₂= mg & ~T ₁= 3 ~T ₂ & ~T ₂ [ 3 ₁+ ₂ ]= mg & for ₁=60^ & ₂=30^ & T ₂= mg 2 aligned
