The newton is the SI unit for force; it is equal to the amount of net force required to accelerate a mass of one kilogram at a rate of one meter per second squared.
The decrease in gravitational potential energy of the system is given by
where
m is the mass, g is the gravitational acceleration, and 
is the variation of height of the system.
also corresponds to the weight of the diver, therefore if we rearrange the equation and we use 
and 
, we can find her weight:
Answer : the box will move backwards with a force 10 N
Explanation :
F1 = 20 N
F2 = 30 N
F = F2 - F1 = 30 - 20 = 10 N
