A concave mirror of focal length ' f ' produces an image ' n ' time the size of the object. If the image is real, then the distance of the object from the mirror is

Options

  1. A( n -1) f
  2. B( n-1 n ) f
  3. C( n +1 n ) f
  4. D( n +1) f

Correct answer

C. ( n +1 n ) f

Step-by-step solution

As the image is real and inverted Magnification, - n = - v u where u = distance of the object v=n u By mirror formula, array ll & 1 f = 1 v + 1 u & 1 f = 1 nu + 1 u & u = ( n +1 n ) f array
