Heavy rain caught a teamer on his way back home from school On reaching home, he emptied his backpack and hung his backpack on the washing line
between two vertical parallel poles. The bag remains in equilibrium. He
realised that the angle belween the washing line and pole B is 50 On further
investigation he noted that force on the washing line between his bag and
pole Als 7,51 N as shown in the diagram below:

21 Draw a vector diagram showing at least one angle and all forces acting
on the bag
22 Write down the magnitude of the resultant of all forces acting on the
bag
23 Name and explain the principle you used to answer question 2.2
(2)
Calculate the mass of this wet bag'if the force on the washing line
between the bag and pole Als 7,51 N
25 When the bag is completely dry, the washing line becomes more
contracted (more horizontan) How would the magnitude of Fo change?
