Q69.The plane which bisects the line joining the points (4, −2, 3) and (2, 4, −1) at right angles also passes through the point : (1) (0, −1, 1) (2) (4, 0, −1) (3) (4, 0, 1) (4) (0, 1, –1)

What This Question Tests

This question requires finding the equation of a plane that is the perpendicular bisector of a line segment. It tests the ability to use midpoint, direction ratios, and the normal vector to form the plane's equation and then check which point lies on it.
