Question

When two forces of magnitude 5N each act on a body in the west direction then the resultant force on the body is____ in the ____ direction .

Answer 1

Answer:

When two forces of magnitude 5N each act on a body in the west direction then the resultant force on the body is zero in the opposite direction.

Explanation:

The resultant of the two forces of 5N each acting on a body in opposite direction is zero because if the first force F1 is directed at zero degrees, the second force F2 is directed at 180 degrees. The cosine of zero degrees F1 is 1.0000 and the cosine of 180 degrees F2 is -1.0000. Adding 1.0000 and -1.0000 results to zero.

If F1 = 5N acting at 60 degrees and F2 = 5N acting at 240 degrees will have a resultant of zero because the cosine of 60 degrees is 0.5000 and the cosine of 240 degrees is -0.5000. Adding 0.5000 and -0.5000 gives a sum of zero. The angles 60 degrees and 240 degrees are opposite each other in the unit circle.

Answer 2

• From the question, the correct answer is zero and opposite.

• As we know when two forces of 5N each acting on a body in opposite direction.

• Then the resultant force is zero on the body.

• If F1 force is directed at 0°, and the second force F2 is directed at 180°.

• As we know 0° F1 is 1.0000 and 180° F2 is -1.0000. by adding 1.0000 and -1.0000 results to zero.

• When two forces of magnitude 5N each act on a body in the west direction then the resultant force on the body is zero in the opposite direction.
