A boy is pulling a load of 150 N with a string inclined at an angle of 30° to the horizontal. If the tension in the string is 105 N, the force tending to lift the load off the ground is: √√3 and tan 30° = 2 (sin 30° = cos 30° = A 255 N B 202.5 N D 75 N E 52.5 N. √√3 C 105 N 2 (SC/GCE). solution please​
