Multiple choice

An infinite soil slope with an inclination of 35^o is subjected to seepage parallel to its surface. The soil has c' = 100 kN/m² = f' = 30^o. Using the concept of mobilised cohesion and friction, at a factor of safety of 1.5 with respect to shear strength, the mobilised friction angle is
