A baby grand piano with a mass of 284 kg hangs from three cables as shown. The angle between the horizontal and the left cable is 27.0° The angle between the horizontal and the right cable is 45.0° What is the tension in the right cable? Use g=9.80 m/s2 and answer in kN by dividing you
answer by 1000.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
