A retaining wall 6m high supports a backfill with a surcharge angle of 10°. The back of the wall is
inclined to the vertical at a positive batter angle of 5°. If the angle of wall friction is 7°, then the
resultant active earth pressure will act at a distance of 2 m above the base and inclined to the
horizontal at an angle of
(A) 7°
(B) 10°
(C) 12°
(D) 17
