ans (B) 8N


Beacause the maximum value of the magnitude of resultant vector of 10N and 6N ( 10 + 6 = 16N) can be 16N if the angle between the vector is 0 degree and the minimum value of magnitude of resultant vector can be 10 - 6 = 4N if the angle between the vector is 180 degree

max=10+6 = 16N


 


min = 10-4 = 4 N


 


hence only option C is satisfying the conditions.

sum is given by root( A^2 + B^2 + 2.A.Bcosx)=(136 + 120cosx)
Hence ans is (b)8N ans.
