The ultimate load capacity of a 10 m long concrete pile of square cross-section 500 mm × 500 mm driven into a homogeneous clay layer having undrained cohesion value of 40 kPa is 700 kN. If the cross-section of the pile is reduced to 250 mm × 250 mm and the length of the pile is increased to 20 m, the ultimate load capacity will be
