p-fluoro benzoic acid
see. in case of m- nitro benzoic acid, both -COOH and -NO2 groups are e repelling and so they will create high e density at carbon atom equidistant from them.........................ie .................the ortho position
on contrary , p-acid will not create high e density at any particular atom and so removing of e shud be easy in here then at m- acid
