Mathematics for IGCSE & O level - Vectors (Section 3 - No. 16)
Given that the point A has position vector a and B has position vector b, what expression gives the position vector of the midpoint M of AB?
a + b
b - a
1/2(a+b)
1/2(b-a)
स्पष्टीकरण
Midpoint M = (A + B)/2, therefore, the position vector = 1/2 (a+b)
