Question

Two persons hold a rope of negligible weight tightly at its ends so that it is horizontal. A 15 kg weight is attached to the rope at the mid point which is now no longer remains horizontal. The minimum tension required to completely straighten top is

A. 15 kg

B. 15/2 kg

C. 5 kg

D. Infinitely large

If you know than answer and if not than skip don't spam please!!!​

Answer 1

Answer:

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/2sinx, where x=0

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

Then, the amount of tension required is infinite.
