Two persons are holding a rope of negligible weight tightly at its end

1.	Two persons are holding a rope of negligible weight tightly at its end so that it is horizontal . A 15 kg weight is attached to the rope at the mid point which now no longer remains horizontal. The minimum tension required to completely straighten the rope is
Answer» The TENSION REQUIRED to bring the string into horizontal position can be found out using the following formulae. 2Tsinx = mg The following equation is true for body which attains equilibrium. Also, when the body will be in equilibrium the ANGLE formed will be 0. Therefore, T = mg/2sin x , where x= 0 T = mg/ 2 sin 0, where the value of sin0 = 0 Then, the amount of tension required is infinite.

Answer»

The TENSION REQUIRED to bring the string into horizontal position can be found out using the following formulae.

2Tsinx = mg

The following equation is true for body which attains equilibrium. Also, when the body will be in equilibrium the ANGLE formed will be 0.

Therefore,

T = mg/2sin x , where x= 0

T = mg/ 2 sin 0, where the value of sin0 = 0

Then, the amount of tension required is infinite.
