The resultant of two forces is 50N. If the forces are perpendicular to each other and one of them makes an angle 30° with the resultant. Find its magnitude.

A. 100.0N

B. 57.7N

C. 25.0N

D. 43.3N

QUICK ANSWER…

D

EXPLANATION…

The resultant of two forces is 50N. If the forces are perpendicular to each other and one of them makes an angle 30° with the resultant. Find its magnitude.

Assuming the two forces are AB and AC, BC will be the resultant, and AC will be the component that makes an angle 30° with the resultant. From the diagram above, AC will obviously be = 50cos30 = 43.3N

Now for the right answer to the above question:

  1. Option A is incorrect.
  2. Option B is incorrect.
  3. C is incorrect.
  4. D is the correct answer.
