Q 1.9) A system has two charges qa = 2.5 x C and qB -2.5 x C located at points A: (0,0,- 15 cm) and B: (0, 0, + 15 cm), respectively. What are the total charge and electric dipole moment lof the svstem?
Both the charges can be located in a coordinate frame of reference asS shown in the given figure. At A, amount of charge, q At B, amount of charge,
The total charge of the system,
Distance between two charges at points A and B,
d= 15 + 15 = 30 cm = 0.3 m
Electric dipole moment of the system is given by,
null m along positive Z-axis
Therefore, the electric dipole moment of the system is C m along the positive z-axis.
