Three people located at a, b, and c pull on ropes tied to a ring. find the magnitude and direction of the force with which the person at c must pull so that no one move

Step-by-step explanation:

Three forces A, B and C pull on ropes tied to a ring such that ring  is in equilibrium.

For the ring to be in equilibrium the force must be concurrent i.e. there line of action must be passed through a single point.

There is no net force when  forces are concurrent.

When all three forces are equal then they should be at angle of  to each other.

you need a common difference between consecutive terms to be constant, like 1,2,3,4 or 2,4,6,8, or 1,3,6,9

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer
