The equation of the plane in normal form passing through the point A (a^{-}), parallel to a vector b^{-} and containing a vector c^{-} is

Correct Answer is : −r.−b×−c|−b×−c|=[−a−b−c]|−b×−c|

r.{c^{-}\timesa^{-}}/{|c^{-}\timesa^{-}|}={|a^{-}\timesb^{-}|}/{|a^{-}\timesc^{-}|}

r^{-}.{a^{-}\timesb^{-}}/{|a^{-}\timesb^{-}|}={[a^{-}b^{-}c^{-}]}/{|b^{-}\timesc^{-}|}

r^{-}.{b^{-}\timesc^{-}}/{|b^{-}\timesc^{-}|}={[a^{-}b^{-}c^{-}]}/{|b^{-}\timesc^{-}|}

r^{-}.[a^{-}b^{-}c^{-}]a^{-}={|b^{-}\timesc^{-}|}/{|a^{-}\timesc^{-}|}
