Consider the following statements:
Assertion (A): the plane y + z + 1 = 0 is parallel to x-axis.
Reason (R): normal to the plane is parallel to x-axis.
Of these statements:
Answer & explanation
Correct answer: option 3
Given plane y + z + 1 = 0 is parallel to x-axis as 0.1 + 1.0 + 1.0 = 0
but normal to the plane will be perpendicular to x-axis.
Hence (3) is the correct answer.
