A small object is placed on the principal axis of a convex mirror of focal length 10cm . Determine the position of the image when the object is 15cm from the mirror.

v = 6 cm

Explanation:

We have,

A small object is placed on the principal axis of a convex mirror of focal length 10 cm. The focal length of a convex mirror is positive. So, f = +10 cm

It is required to find the position of the image when the object is 15 cm from the mirror. Using mirror's formula :

v is image distance

Hence, the image will formed at a distance of 6 cm form the mirror.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

f is prop to m1xm2 double m1 double force
