The mass of the Mars exploration rover is 1063 kg . The gravity on Mars is about 0.38 that of Earth. Assuming the same slope, on which planet will the normal force exerted on the rover by the planet's surface be the greatest

i'm thinking more like energy

im guessing the west of station b

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
