Question

16. Two force vectors F1, andF2 each of magnitude
10 N act at a point at an angle of 60degree. The
magnitude of resultant force vector is
(1) 10 N
(2) 10√3N
(3) 20 N
(4) 20√3 N​

Answer 1

Explanation:

F=F1F2cos(tita)

F=10×10×1/2=50N is resultant force

Answer 2

Explanation:

according to the the above solution in the above figure the correct answer is 10✓3 N

i.e.. option (c)
