An effort of 2 kN is required just to move a certain body up an inclined plane of angle 15°, the force acting nlel to the plane. If the angle of is agnation of the plane is fiade 20°, the effort required, againaplied parallel to the plane, is found to be 2.3 kN. Find the weight of the body and the coefficieraeo friction. (A) 3.9 kN, 0.258 (C) 3.8 kN, 0.24 (B) 4.5 kN, 0.26 (D) 3.8 kN, 0.268
