1.	If →a ′=^i+^j,→b ′=^i+^j+2^k and →c ′=2^i+^j−^k. Then altitude of the parallelopiped formed by the vectors →a,→b,→c having base formed by →b and →c is (→a,→b,→c and →a′,→b′,→c′ are reciprocal system of vectors)
Answer» If $\to a^{'} =^i +^j, \to b^{'} =^i +^j + 2^k$ and $\to c^{'} = 2^i +^j -^k$ . Then altitude of the parallelopiped formed by the vectors $\to a, \to b, \to c$ having base formed by $\to b$ and $\to c$ is $(\to a, \to b, \to c$ and ${\to a}^{'}, {\to b}^{'}, {\to c}^{'}$ are reciprocal system of vectors)
