Question

One force of 100 units acts on an object. Another force of 80 units acts on the object at a 40 degrees angle from the first force. Find the magnitude of the resultant force?
A) 140 degree
B) 169.283 units
C) 28,656.711 units

Answer 1

Answer:

B) 169.283 units

Step-by-step explanation:

Among the given answers, this is the only one that makes sense. A gives an option which is not what the question asks for. It asks for magnitude, not direction. C could not be the answer, as no function of the two forces would reasonably result in such a force. B is the only one which works in this situation.

Answer 2

The correct answer is B
