Question

find the net force for 9n and 8n in opposite directions​

Answer 1

Answer:

mark me the brainliest

Explanation:

The net force acting on an object is the combination of all of the individual forces acting on it.

If two forces act on an object in opposite directions, the net force is the difference between the two forces. ...

If two forces act on an object in the same direction, the net force is the sum of the two forces.

Answer 2

Answer:

n

Explanation:

As the forces are at opposite directions, the angle between them is 180 degree.

Net force =

Magnitude of net force  $\sqrt{a^{2} +b^{2} + 2abcos\alpha } \\\sqrt{(9n)^{2} +(8n)^{2} + 2*9n*8n*cos(180) } \\\sqrt{81n^{2} +64n^{2} + 144n^{2} (-1) } \\\sqrt{145n^{2} - 144n^{2} }\\\sqrt{n^{2} }\\=n$
