6. A 50 N block is raised 2 m. If the net work done on the block is 50 J, what is the applied force on the block?

The force applied in raising the block to the given height is 25 N.

The given parameters:

The force applied in raising the block to the given height is calculated as follows;

Thus, the force applied in raising the block to the given height is 25 N.

F = 75[J]

Explanation:

We know that work is defined as the product of force by distance.

In this way we have two forces, the weight of the block down, and the force that bring about the block to rise.

where:

W = work = 50 [J]

d = distance = 2 [m]

Fweight = 50 [N]

Fupward [N]

tube or goog will be great resources to find the answer to the question that you're asking

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
