Type: MCQ-numerical-Medium-Class 11
A uniform rod of mass 20 kg and length 5 m leans against a smooth vertical wall making an angle of 60° with it. The other end rests on a rough horizontal floor. The friction force that the floor exerts on the rod is (take g = 10 m/s²)
A
100 N
B
100√3 N
C
200 N
D
200√3 N
Correct Answer
Option B
Detailed Explanation
