Point charges q1=? 4.10nC and q2=+ 4.10nC are separated by distance 3.20mm , forming an electric dipole.
a) Find the magnitude of the elictric dipole moment.
b) What is the direction of the dipole moment?
c)The charges are in a uniform electric field whose direction makes an angle 37.0? with the line connecting the charges. What is the magnitude of this field if the torque exerted on the dipole has magnitude 7.60×10?9N?m ?
