Solve the all parts of given question:
Question: Point charges q1=- 4.00nC and q2=+ 4.00nC are separated by a distance of 3.60mm, forming an electric dipole.
Part I: Find the magnitude of the electric dipole moment.
Part II: The charges are in a uniform electric field whose direction makes an angle of 36.0 degree with the line connecting the charges. What is the magnitude of this field if the torque exerted on the dipole has magnitude 7.70 × 109 Nm?
Please do a step by step solution since I'm kind of lost with this question.
