A system has two charges and is located at points and respectively. What is the total charge and electric dipole moment vector of the system?
Step 1. Given Data,
Step 2. Formula used,
is the length of the dipole
is the given charge
Step 3. Calculating the total charge,
The amount of charge at A,
The amount of charge at B,
The total charge of the system is
Hence the total charge is .
Step 4. Calculating the electric dipole moment
Distance between points A and B,
The electric dipole moment of the system,
along the positive z-axis.
Hence, the electric dipole moment of the system is along the positive z-axis.
