Answer :
=> To get a virtual image in concave mirror , then the object must be placed b/w ( between ) F and P.
=> F stands for focus.
=> P stands for pole.
=> F is the point where the marginal rays meet in concave mirror and tend or appear to meet in convex mirror.
=> P is the geometric centre of the spherical mirror( here : concave mirror )
