The polar co-ordinates of P are 2 . π 6 . If Q is the image of P about the X-axis then the polar co-ordinates of Q are…

Options

  1. A2 , 5 π 6
  2. B2 , π 6
  3. C2 , π 3
  4. D2 , 11 π 6

Correct answer

D. 2 , 11 π 6

Step-by-step solution

We have, polar coordinates of P are 2 , π 6 If Q is the image of P about the X-axis ∴ Q = 2 , - π 6 ⇒ Q = 2 , 11 π 6
