@vivaangandhi how 2 image is 10 cm

@urvashi here it is given that object is placed 5cm from M2, and given separation blw mirrors is 15 cm so to find image in M1, we should subtract 15 5 as the object is already placed 5cm away from M2 and the image in the M1 will be formed 10cm away as u= v

@varsha can u tell me any other method
