Two forces of 5kg wt and 10kg wt are acting at an inclination of 120
Find the magnitude and direction of resultant force.
Since you don't specify either force's direction,
let the 5N force act in the x direction. Its vector value is then (5,0)
The other force is then (-5,5√3)
Add them together to get (0,5√3)
That's 5√3 at right angle to the N force.
