Questions  

Which pair of the following forces will never give resultant force of 2 N?

a
2 N and 2 N
b
1 N and 1 N
c
1 N and 3 N
d
1 N and 4 N

detailed solution

Correct option is D

If two vectors A and B are given then range of their resultant can be written as (A - B) ≤ R ≤ (A + B).i.e., Rmax=A+B and Rmin=A−BIf B = 1 and A = 4 then their resultant will lies in between 3 N and 5 N. It can never be 2 N.
