Let p → , q → , r → , s → are non-zero vectors in which no two of them are perpendicular and no three of them are coplanar. If q → × r → ⋅ p → × s → + r → × p → ⋅ q → × s → = k p → × q → ⋅ s → × r → , then the value of k 2 is equal to

Step-by-step solution

q → × r → ⋅ p → × s → = q → ⋅ p → q → ⋅ s → r → ⋅ p → r → ⋅ s → = q → ⋅ p → r → ⋅ s → - q → ⋅ s → r → ⋅ p → … i r → × p → ⋅ q → × s → = r → ⋅ q → r → ⋅ s → p → ⋅ q → p → ⋅ s → = r → ⋅ q → p → &#
