Figure shows two plane mirrors parallel to each other and an object O placed between them. Then the distance of the first three images from the mirror M2 will be : (in cm)


(1) 5, 10, 15             (2) 5, 15, 30              (3) 5, 25, 35                     (4) 5, 15, 25

the first image will be at 5 cm inside the M2the second image is 10 cm inside the M1 hence distance from M1 is 10+10+5=25 cm and the next image will be inside the M2 of the second image in M1 is 25+10=35 cm henceoption 3regards
