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.

8N as net force lies between  lies between the range 4N and 16N

IT CAN BE EQUAL TO 2N FOR A SMALL ANGLE BETWEEN THEM

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

The answer is 2 newtons I think this is the right answer because its not asking minimum or maximum so according to me the right answer is A

From the rules of vector
A-B≤R≤A+B
 
Here, A = 10 and B= 6. So, 
10-6≤R≤10+6
4≤R≤16
 
Here, R is the resultant vector.So it should be below 16 and greater than 4. And from the option the favourable answer is 8 
 
So option (B) is correct!!!
 
Cheers!

Answer to this question is option b. 
   10+6=16 and 10-6=4. Therefore maximum is 16 and minimum is 4.  So answer will lie between 16 and 4.
