Question

Two force vectors , and F., each of magnitude
10 N act at a point at an angle of 60°. The
magnitude of resultant force vector is
(1) 10 N
(2) 103 N
(3) 20 N
(4) 2013 N​

Answer 1

Explanation:

The resultant force vector, R = (10)^2 + (10)^2 + 2(10)(10)cos 60

=> 100 + 100 + 100

=> 300 N
