A rectangle with its dimensions is as shown. A magnetic mono pole of pole strength ' $m$ ' is placed at the point ' $A$ ' and another pole of strength ' $5 m$ ' is placed at the point ' $B$ '. The magnetic force acting between them is ' $F$ '. If magnetic pole at the point ' $B$ ' is moved to the point ' $C$ ', find final magnetic force acting between them.
