A body is under the action of two forces 7N and 10N. Find the resultant of the two forces if: 1.) The forces are parallel and act in the same direction 1.) The forces are inclined at an angle of 60° to each other. .2) The forces act at 90° to each other.

The answer is below

Explanation:

1) The resultant force of two forces acting in the same direction is equal to the sum of the two magnitudes. Therefore:

Resultant force = 10N + 7N = 17 N

2) The resultant force(R) between two forces A and B at an angle θ is given by:

3) The resultant force (R) between perpendicular forces (90°) A and B is given by:
