![### Problem Statement
A small, rigid object carries positive and negative 2.00 nC charges. It is oriented so that the positive charge has coordinates (−1.20 mm, 1.60 mm) and the negative charge is at the point (1.50 mm, −1.30 mm).
1. **Part (a)**:
- **Question**: Find the electric dipole moment of the object.
- **Answer**: \(\boxed{\phantom{space}} \ \mathrm{C \cdot m \ \hat{\imath}} + \boxed{\phantom{space}} \ \mathrm{C \cdot m \ \hat{\jmath}}\)
2. **Part (b)**:
- **Question**: The object is placed in an electric field \(\mathbf{E} = (7.80 \times 10^3 \ \hat{\imath} - 4.90 \times 10^3 \ \hat{\jmath}) \ \mathrm{N/C}\). Find the torque acting on the object.
- **Answer**: \(\boxed{\phantom{space}} \ \text{N} \cdot \text{m} \ \boxed{\text{---Select---}}\)
3. **Part (c)**:
- **Question**: Find the potential energy of the object-field system when the object is in this orientation.
- **Answer**: \(\boxed{\phantom{space}} \ \mathrm{J}\)
4. **Part (d)**:
- **Question**: Assuming the orientation of the object can change, find the difference between the maximum and the minimum potential energies of the system.
- **Answer**: \(\boxed{\phantom{space}} \ \mathrm{J}\)
### Explanation of Graphs/Diagrams
In this problem, no specific graphs or diagrams are provided. However, it involves calculating various properties of an electric dipole in an electric field. The main components are:
- The coordinates of the charges, which describe the position of the positive and negative charges in a millimeter scale.
- The electric field vector, which has been given in unit vectors \(\hat{\imath}\) and \(\hat{\jmath}\).
The calculations will likely involve using these coordinates and the electric field to determine the dipole moment, torque, and potential energy based on](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb545c1da-5189-4db2-a5be-87bfeb3e801e%2Fe36bf664-c8d7-45c4-b4cc-7df27def2ed2%2Fhir095s_processed.jpeg&w=3840&q=75)
