What is the potential energy of a 100 kg object that is suspended motionless at 30 meters above the ground?

I'm having some difficulty seeing the diagram clearly.but the question says there's a net inward force on the object.so we know right away,  from newton's 2nd law of motion, thatthat baby is accelerating.  it doesn't even matter which way thenet force is pointing.  if there's any net force, then either theobject's speed or else its direction must be changing.

Decrease the surface area of the object and also decrease the concentration which will allow the particles to collide faster
