b) The physical properties of an existing slope are as shown in Table Q.3(b). The soil properties of the soil are as follow: unit weight= 19 KN/m', cohesion=10 kPa, angle of intenal friction 30°. Determine the factor of safety (FS) of the slope by using the Bishop's Method. Complete a maximum of three iterations and correct the answer to three decimal places.
