A force of 12N acts to the left on a body and a force of 16 N acts to the right . The size and direction of resultant force is 1)4N
2)28N to the right
3) 4 N to the right

Explanation:

The force acting to the right of the body is acting in the positive x direction while the force acting to the left of the body is acting in the negative x direction.

If a force of 12N acts to the left on a body and a force of 16 N acts to the right, force acting to the left will be -12N while that acting to the right will be +16N.

The resultant force acting on the bod will be the sum of the two forces.

Resultant = -12N+16N

Resultant = 4N

The direction of the resultant force will be towards the right since the resultant is a positive value.

that would be b i just took the test : )
