Question

Two spheres are hanging from the ceiling  Both spheres have a mass of 5kg. Find the tension in both ropes (the rope is connected to the celling then sphere one is attached to it then under sphere one is another rope holding sphere two)

Answer 1

The tension in the rope connecting the two spheres:

$$T_2=mg=5·9.8=49\text{ N}.$$

The tension in the rope connecting the upper sphere to the ceiling:

$$T_1=2mg=98\text{ N}.$$
