Question

In Fig. 3.17, a block of weight 15 N is hanging
from a rigid support by a string. What force is
exerted by
W-15 N
Fig. 3.17
(a) block on the string,
(b) string on the block.
Name them and show them in the diagram.​

Answer 1

Answer:

the forces acting on the block are the weight (due to gravitation) and the tension force in the string pulling it upwards. Since the block is stationary and in equilibrium, the two forces are equal and opposite. Hence, the tension force exerted by the string on the block = weight = 15 N.
