Four parrots are pulled on a frictionless surface using a cord. The tension in two of the cords are T2=111N, T4=222N and the mass of the 3 parrots are given as, M1=12 KG, M3=15kg, M4=20kg. Find the mass of 2nd parrots.
Step 1: Given data
The tension of two of the cords, ,
Mass of three parrots,
Demonstrating with the help of diagram
Step 2: Calculating the mass of parrot.
Let be the mass of the unknown parrot.
Tension for the whole system of parrots
Dividing both the equations, we get
Therefore, the mass of parrot is
