Answer:
W = 47.04 N
Explanation:
It is given that,
A block of mass 4.8 kg is suspended by the pulley and it is assumed that it is frictionless and the mass of the strings to be negligible.
We need to find the reading of the spring scale if the system is in equilibrium.
At this position, the scale reading is equal to the weight of the block such that,
W = mg, where g is the acceleration due to gravity
W = 4.8 kg × 9.8 m/s²
W = 47.04 N
So, the reading of the spring scale is 47.04 N.
