A uniform ladder of mass 10 kg leans against a smooth vertical wall making an angle 53 with it. the other end rests on a floor. Find the normal force and frictional force that the floor exerts on the ladder. Torque about B is taken as N 1 (AO)=W(CB) Please explain the concept behind the above equation.

calculate  all the forces acting on center of mass of rod & net torque about center of mass

put both of these equal to zero (because there is neither translational nor rotational motion )and

then u will have 2 equations and two variables..

solve these equations and get the ans...
