Question
The maximum and minimum magnitudes of the resultant of two given vectors are 17 units and 7 units respectively. If these two vectors are at right angles to each other, the magnitude of their resultant is
Answer: Option D
:
D
Rmax = A + B = 17 when θ = 0∘
Rmin = A - B = 7 when θ = 180∘
by solving we get A = 12 and B = 5
Now when θ = 90∘ then R = √A2+B2
⇒R=√(12)2+(5)2 = √169 = 13
