A smooth backed vertical wall is 6.3m high and retains a soil with a bulk unit weight of 18 KN/m^3 and angle of friction 18 degrees. The top of the soil is level with the top of the wall and is horizontal. If the soil surface carries a uniformly distributed load (surcharge) of 4.5 KN/m^2, what is the difference in active moment at the base of the wall with surcharge and without surcharge.
