[figure] A body of mass 1 kg is suspended with the help of two strings making angles as shown in figure. Magnitudes of tensions T1 and T2, respectively, are (in N) : (Take acceleration due to gravity 10 m/s2)
- 5 3, 5
- 5 3, 5 3
- 5, 5
- 5, 5 3
Answer
(1) 5 3, 5
Solution
The body is in equilibrium; T1 makes 60 and T2 makes 30 with the horizontal.
Horizontal: T1 60 = T2 30
T12 = 3 T22 T1 = 3 T2
Vertical: T1 60 + T2 30 = mg = 10
3 T2 32 + T22 = 10
2T2 = 10 T2 = 5 N
T1 = 5 3 N
Answer: (1)
