Question

Q 6. The block of mass 'm' equal to 100 Kg is being pulled by a horizontal force F=2 mg applied to a string as shown in figure (Take g=10 m/s2). The pulley is massless and is fixed at the edge of an immovable table. What is the value of force exerted by the supporting cable(rod) on the pulley (in Newton)(A) 3mg (B) 4mg (C) 2√2mg (D) 2mg
