Let the plane (2 x)/(k)+(2 y)/(3)+(z)/(3)=2 pass through the point...

Let the plane 2xk+2y3+z3=2\frac{2 x}{k}+\frac{2 y}{3}+\frac{z}{3}=2 pass through the point (2,3,−6)(2,3,-6). What are the direction ratios of a normal to the plane?

Options

  1. A⟨3,2,1⟩\langle 3,2,1\rangle
  2. B<2,3,6⟩< 2,3,6\rangle
  3. C<6,3,2⟩< 6,3,2\rangle
  4. D<1,2,3⟩< 1,2,3\rangle

Correct answer

A. ⟨3,2,1⟩\langle 3,2,1\rangle

Step-by-step solution

Direction ratios of a normal are <3,2,1>< 3,2,1 >
