Question

The maximum resultant of two vector is 26 unit and minimum resultant is 16 unit, then what is the magnitude of vector

Answer 1

Let two vectors be A and B
maximum vector = A+B
A+B= 26..............i
similarly for minimum vector it will be
A-B=16.......................ii
from i and ii we get
A+B=26
A-B=16
2A=42
A=21
so .B =5
