Dipole Moments

Please show all work and show all equations used so I can understand completely.

1) A uniform electric field of 300N/C makes an angle of 25 degrees with the dipole moment of an electric dipole. If the torque exerted by the field has a magnitude of 2.5*10^-7N.m, the dipole moment must be ___?

2) The dipole moment of a dipole in a 300 N/C electric field is initially perpendicular to the field, but it rotates so it is in the same direction as the field. If the moment has a magnitude of 2*10^-9C.m the work done by the field is ___?

3) A total charge of 6.3*10^-8C is distributed uniformly throughout a 2.7cm radius sphere. The volume charge density is ___?
