Answer:
Explanation:
When two forces act in the same direction , they add up and when they act in opposite direction , they subtract .
2 forces each of 50 N act in same direction , so they will add up to give resultant force of 100 N . Now third force acts in opposite direction so 100 N and - 90 N will subtract to give total resultant force .
Resultant force = 100 - ( - 90 ) = 190 N
So net force or resultant force = 190 N .
