A uniform of rod of length l is placed symmetrically on two walls as shown in the figure. The rod is in equilibrium. If N1 and N2 are the normal forces exerted by the walls on the rod, then :
N1>N2
N1<N2
N1=N2
N1 and N2 would be in the vertical directions N1N2
A
N1>N2
B
N1<N2
C
N1 and N2 would be in the vertical directions N1N2
D

At equilibrium, N1+N2=mgcosθ
Also τA=0⟹N1(0)+mgl4cosθ−N2l2
mg2cosθ=N2
Thus N1=mg2cosθ
Hence N1=N2
