Answer 1

Answer:

max force = 50 N and min force = 10 N

Explanation:

The given forces exert max. force on the body when they are in same direction. In this case, the resultant force is the sum of the two forces i.e. 50 N.

When the forces act opposite to each other i.e. the angle between them is 180 degrees, the resultant force or net force is the difference of the two forces i.e. 10 N, acting in the direction of the force greater in magnitude.

These are two special cases where we can calculate the resultant force without applying vector law of addition directly.

Hope this was helpful.

Answer 2

Answer:

Max. resultant force when both acted on same direction so, resultant force max. =F1+F2= 20+30=50N

and minimum resultant force is when both acted on a body in opposite direction

so, min. resultant force=30-20N=10N
