A rigid smooth retaining wall of height 7 m with vertical back face retains saturated clay as backfill. The saturated unit weight and undrained cohesion of the backfill are 17.2 kN/m² and 20 kPa respectively. The difference in the active lateral forces on the wall (in kN per m length of wall) up to two decimal places, before and after the occurrence of tension cracks is
