  • question_answer
    The line drawn from (4, ?1, 2) to the point (?3, 2, 3) meets a plane at right angles at the point (?10, 5, 4), then the equation of plane is [DSSE 1985]

    A)            \[7x-3y-z+89=0\]

    B)            \[7x+3y+z+89=0\]

    C)            \[7x-3y+z+89=0\]

    D)            None of these

    Correct Answer: A

    Solution :

               Required plane is, \[7\,(x+10)-3\,(y-5)-(z-4)=0\] or \[7x-3y-z+89=0\].
