Question

If two mirrors are inclined at some angle ©. An object is placed between the two mirrors and there are 5 images formed for an object. Then © maybe
1)45°
2)53°
3)63°
4)75°

Answer 1

generally ,
no of image between two inclined plane found by ---
M = 360°/@
if M = any natural number , then
only this is not occur when object placed bisector of angle of line ,

no of image = (m-1)

now ,
here 5 image formed between two mirror,

so, 5 = M-1
M = 6

so, 6 =360°/@
@ = 360/6 =60°
hence , this is nearly equal to 63° so, answer is 63 °

Answer 2

therefore 63° is the answer
