A mass of 10 kg is suspended vertically by a rope from the roof. When a horizontal force is applied on the rope at some point, the rope deviated at an angle of 45∘ at the roof point. If the suspended mass is at equilibrium, the magnitude of the force applied is ( g=10 ms−2 )
a. 200 N
b. 140 N
c. 70 N
d. 100 N
