When an object of height `'h_(o)'` is placed in front of a pinhole camera, an image of height `'h_(i)'` is formed. If the object is placed at a distance 'u' from the pinahole camera, arrange the following steps to determine the widht of the camera in proper sequence.
(A) Determine the magnification (m).
(B) Note the value of `h_(o)andh_(1)`.
(C) Determine the image distance (v).
(D) Substitute the value of 'm' and 'u' in `m=(v)/(n)` where u is the object distance.
(E) Take the value of 'v' as the width of the camera.

Options

A. BDACE
B. BADCE
C. ECDBA
D. ABCDE

Answer

B

Explanation

Note the value of `h_(o)andh_(i)` (B). Substitute the values of object height `'h_(o)'` and image height `(h_(i))" in "m=h_(i)//h_(o)` (A), then substitute the value of m and u in `m=v//u` (D). Determine the volue of v (C) and tatke this as the which of the camera (E).
