MHT CET 2024 Physics question
A metal rod of weight 'W' is supported by two parallel knife-edges A and B. The rod is in equilibrium in horizontal position. The distance between two knife-edges is 'r'. the centre of mass of the rod is at a distance 'x' from A. the normal reaction on A is
Answer: (D)
Solution
Let the normal reactions be and . Vertical equilibrium: . Taking torques about knife-edge B (distance from A): , because the centre of mass is at distance from A and hence from B. So $ =
