Questions
The maximum and minimum magnitude of the resultant of two given vectors are 17 units and 7 unit respectively. If these two vectors are at right angles to each other, the magnitude of their resultant is
detailed solution
Correct option is D
Rmax = A+B = 17 when θ = 00Rmin=A-B = 7 when θ = 1800By solving we get A = 12 and B = 5Now when θ = 900 then R = A2+B2⇒R = (12)2+(5)2=169 = 13Talk to our academic expert!
