A point object is moving with a speed v in front of an arrangement of two mirrors as shown in figure. If the velocity of image in mirror M 1 with respect to image in mirror M 2 is n(v sin θ ), find n

Correct answer

2

Step-by-step solution

Angle between v ⁡ I 1 & v ⁡ I 2 is 2 θ . Their magnitudes is v . ∴ v I 1 v I 2 = | v → I 1 − v → I 2 | = v 2 + v 2 − 2 v v cos 2 θ = 2 v ⁡ sin θ
