A rod of weight w is supported by two parallel knife edges A and B and is in equilibrium in a horizontal position. The knives are at a distance d from each other. The centre of mass of the rod is at distance x from A. The normal reaction on A is.. And on B is......
A. `N_(A)=2w(1-x//d),N_(B)=wx//d`
B. `N_(A)=w(1-x//d),N_(B)=wx//d`
C. `N_(A)=2w(1-x//d),N_(B)=2wx//d`
D. `N_(A)=wx//d,N_(B)=w(1-(x)/(d))`
