In the design of the retaining wall, both, active earth pressure and passive earth pressure are considered due to soil available on both sides (with different heights) of the R. C. C retaining wall. If the angle of repose, ϕ = 30°, then what will be the relation between the coefficient of active earth pressure (Ka ) and passive earth pressure (Kp )

Ka = 1/3 KP
2
Ka = 3 KP
3
Ka = 9KP
4
