Dear Student

$f o c a l l e n g t h o f c o n v e r g i n g m i r r o r f = 10 c m d i s t n a c e b e t w e e n t h e l e n s e a n d m i r r o r u = - 5 c m e q u a t i o n o f l e n s e \frac{1}{f} = \frac{1}{v} - \frac{1}{u} \frac{1}{10} = \frac{1}{v} + \frac{1}{5} \frac{1}{v} = - \frac{1}{10} v = - 10 c m$

object should be placed at 10 cm from the mirror
