(a) A block of mass m = 3.90 kg is suspended as shown in thediagram below. Assume the pulley to be frictionless and the mass ofthe strings to be negligible. If the system is in equilibrium, whatwill be the reading of the spring scale in newtons? N
(b) Two blocks each of mass m = 3.90 kg are connected as shownin the diagram below. Assume the pulley to be frictionless and themass of the strings to be negligible. If the system is inequilibrium, what will be the reading of the spring scale innewtons? N
(c) A block of mass m = 3.90 kg is in equilibrium on an inclineplane of angle θ = 28.0° when connected as shown in the diagrambelow. Assume the mass of the strings to be negligible. If thesystem is in equilibrium, what will be the reading of the springscale in newtons? N
