the resultant of two vectors at an angle 150° is 10 units and is perpendicular to one vector. the magnitude of the smaller vector is ? Ans= 10√3 Share with your friends Share 7 Neha Gupta answered this vector with greater magnitude = Avector with lesser magnitude = BA2+B2=100because resultant vector is perpendicular to the smaller one.Asin (180-150) = 10A2 = 10A = 20Acos(30) = B20×32 = BB = 103 units. 10 View Full Answer
