Question

What happens when two equal and opposite forces acr on an object?

Answer 1

You mean act right...
So two equal and opposite forces means both are cancelling each other...
Therefore net force on that body is zero means body will not move and it will remain as it is.
You can also say that body is in equilibrium.

Answer 2

HEY BUDDY..!!!

HERE IS UR ANSWER...

______________________

=> the meaning of 2 equal and opposite forces is

⏺️An object is under 2 forces acting oppositely , against each other ..

So

=> Thing net of them

=> F 1 + F2

We know F1 = - F2


=> F 1 + F 2 = 0

It means body will not move . hence at equilibrium...

HOPE HELPED..

HAVE A NICE DAY..
