A plane mirror is inclined at an angle 30^{\circ} with the horizontal surface. A particle is projected from ground (at t=0 ) with velocity V=20 {m} \/ {s} at an angle of 60^{\circ} with the horizontal. The image of particle is observed. (The particle does not collide with the mimor). Then

The time when image is at rest with respect to particle is \frac{2}\sqrt{3} second

The time when the image is at rest with respect to particle is \sqrt{3} second

Path of image of particle as seen by itself is parabolic

Path of image of particle as seen by itself is straight line
