From Vector Given Magnitude and Direction

Vector is a quantity with:

• magnitude and direction

• magnitude

• direction

• none of the above

• a is the position vector of point A

• b is the direction vector of line L

• r is the position vector of all points in L, represented by P(x,y)

• OB + BC = OC

• OA + AC = OC

• CB + B0 = -OC

• OD = 0.5(OA + AC)

Given the vector v = 3i -2j +6 k, the magnitude of a is:
