Magnitude of force exerted on a pulley

WebThe block of mass m kg is being pulled by a horizontal force F = 2 mg applied to a string as shown in figure (Take g = 10 ms − 2). The pulley is massless and is fixed at the edge of an immovable table with a supporting cable. What is the value of force exerted by the supporting cable (rod) on the pulley (in Newton). Webthe magnitude of normal force equals that of friction D the bodies may be rough but they don't slip on each other Medium Solution Verified by Toppr Correct options are B) and D) Generally with friction the contact force, F c=μN but here F c=N, so there in no friction force between the block. Otherwise they may not slip on each other.
