Vector Component

The head of a...

Question

The head of a vector is at coordinate (3, 4, 5) and its tail is at (2, -1, 1). Write the vector.

Open in App

Solution

Position vector = position of head - position of tail
Position vector $\to r = (3^i + 4^j + 5^k) - (2^i -^j +^k)$
$⟹ \to r =^i + 5^j + 4^k$
