Question

If a force of 10 N along+x direction is acting on a object. What other force can be used to balance this force?

Answer 1

A frictional force of 10N on the opposite direction can be used to balance the given force.

Step-by-step explanation:

The net force is the sum of all forces acting on the object in different directions (x,y):

`\sum F_(r) = ma` (1)

Where
`\sum F_(r)` represents the net force, m is the mass and a is the acceleration.

`F_(x) + F{y} = ma` (2)

`F_(x)` is the sum of the forces that are in the x direction, for this particular case
`F_(x)` has to be equal to zero to be balanced.

`F_(x) = 10N - 10N`

`F_(x) = 0`

So a force with the same magnitude but opposite direction is needed (-x).

Hence, a frictional force of 10N in the opposite direction can be used to balance the given force.
