A point object is moving with a speed v before an arrangement of two mirrors as shown in figure. Find the velocity of image in mirror M_(1) with respect to image in mirror M_(2)

Answer»

2v SIN (`THETA`/2)
V sin (`theta`/2)
2v cos (`theta`/2)
v cos (`theta`/2)

Solution :(a) VELOCITY of image , `v_(r)=sqrt(v^(2)+v^(2)-2vcdotvcdotcostheta)`
=2v`sin(theta//2)`
