A lens whose radii of curvature are different is forming the image of an object placed on its axis. If the surfaces of the lens facing the object and image are interchanged will the position of the image change?

No, we know that
` 1/f = (mu_(21) - 1) ((1)/(R_1) - (1)/(R_2))`
When we interchange `R_1` and `R_2` the value of f does not change except for the sign. So, the image will be formed at the same position.
