Question

Two object whose masses are 5 kg and 10 kg are suspended by strings, as shown in the figure. Find the tension on each string.

Answer 1

If a 5-kg body is attached to the ceiling with a string and a 10-kg body is attached by means of a string to the 5-kf body, the tension in the first string will be

$$T_5=g(M_5+M_{10})=147\text{ N},\\ T_{10}=gM_{10}=98\text{ N}.$$
