The image formed by a concave mirror is virtual, erect and magnified. The position of object is:(a) at focus (b) between focus and centre of curvature(c) at pole (d) between pole and focus
(d) Between the pole and the focus
Explanation
For an object placed between the pole $(P)$ and the focus $(F)$, the image formed by a concave mirror is virtual and erect, bigger than the object (enlarged) and behind the mirror.

The image formed by a concave mirror is observed to be virtual, erect and larger than the object. Where should be the position of the object?$(a)$. Between the principal focus and the centre of curvature$(b)$. At the centre of curvature$(c)$. beyond the centre of curvature$(d)$. Between the pole of the mirror and its principal focus.
