The classic image problem in electromagnetism involves a grounded infiniteconducting plane and a point charge. The force of attraction between the pointcharge and the plane is identified using an equivalent-field picture of animage charge with opposite sign equidistant behind the plane resulting in a1/{\it r}$^{\rm 2}$ force of attraction between the original charge and theplane. If the point charge is released from rest it will reach the plane in atime $\tau$. This time $\tau$ has not been calculated correctly up to now.Clarification of the inconsistency is presented along with a correct solutionto the classic image problem. Other electromagnetism problems are mentionedwith attractive 1/{\it r}$^{\it n}$ forces (where {\it n} $\ge$ 1). Suchsituations arise between a point charge and a line charge (1/{\it r}), betweena line charge and a point dipole (1/{\it r}$^{2}$), between a point charge anda point dipole (1/{\it r}$^{3})$, and between a point dipole and a second pointdipole (1/{\it r}$^{4}$).
