Explanation:
k = Coulomb constant = 
r = Distance = 
E = Electric field = 1150 N/C
Electric field is given by

Number of electrons is given by

Number of excess electrons is 10573375000
r = 0.115+0.15 = 0.265 m

The electric field is 
yes ,each piece will remain a magnet because the small pieces will cut into north and south
