g newton's law of gravitation states that two bodies with masses m and n attract each other with a force f=gmn/r^2 where r is the distance betweenthe bodies and g is the gravitational constant. if one of the bodies is fixed, find the work needed to move the other from r=a to r=b

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

im doing peak rn so sry if its wrong

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
