Force is a vector quantity.
So, the resultant force depends on the angle between these two forces.
There are two forces of 6N and 8N.
If both the forces are in same direction,the resultant force = 6+8= 14 N
If the forces are in opposite direction,then resultant force is 2N, in the direction of 8N.
So, the maximum force for this pair of forces is, 14 N and minimum force is 2N.
From the given four options, the correct answer is 11 N.
