Equation of a Plane : Vector Form

If p,q,r is r...

Question

If $\to p, \to q, \to r$ is reciprocal system of vector triad $\to a, \to b$ and $\to c,$ then $[\to a \to b \to c] [\to p \to q \to r] =$

Open in App

Solution

As $\to p, \to q, \to r$ is reciprocal system of vector triad $\to a, \to b$ and $\to c$
$\Rightarrow [\to a \to b \to c] = \frac{1}{[\to p \to q \to r]}$
$\Rightarrow [\to a \to b \to c] [\to p \to q \to r] = 1$
