Question

two force of 8 kg and 10kg are acting at an angle 60. find out the resultant force.​

Answer 1

forces can't be in kg .so i am assuming it in newton.

$|r| = \sqrt{ {x}^{2} + {y}^{2} + 2xy \cos( \alpha ) }$

x=8N

y=10N

$\alpha = 60$

insert values of x,y and alpha in the formula.

and your answer will be √244 newton.

hope it helps.
