Question

Sovle this problem Two forces of 80 N and 70 N act simultaneously at a point. Find the resultant force if the angle between them is 150°

Answer 1

hello here is your answer

f 1 =80 N

f 2 = 70N

F=√f 1² +f 2²+f 1. f 2 cosΦ

F=√6400+4900+5600cos 150°

F=√ 11300+5600 . -√3 by 2

F =√11300+2800.-√3

F=10√113-28√3

F=10√113-(28×1.73)

F=10√113-48.44

F=10√64.56

F=10×8.034

F 80.34N

Answer 2

Answer:

150 N

Step-by-step explanation:

we add the two forces act when they are on a same point on the surface of an object so,

80 +70 = 150
