Question

An object has one force acting on it. it is a 33-newton force pointing downward. to create a net force of zero on the object, which force must be applied to it?

Answer 1

to get a net force of zero you need 33 newton force pointing upwards.

Answer 2

For this case, the first thing we are going to do is define a reference system.

We define the vertical axis of the reference system, pointing upwards.

Therefore, doing summation of forces in vertical direction we have:

`image`

Then, since we want the net force to be equal to zero, then:

`image`

From here, we clear the force that we must apply on the object:

`image`

The positive sign means that the force points upwards.

Answer:

to create a net force of zero on the object you must apply:

33 Newton upwards.
