Final answer:
The electric field of a dipole at a point perpendicular to the middle of the two charges can be calculated using the formula E = (kQd) / (r^3).
Step-by-step explanation:
The electric field of a dipole at a point perpendicular to the middle of the two charges can be calculated using the formula:
E = (kQd) / (r^3)
where E is the electric field, k is the Coulomb constant (9 x 10^9 Nm^2/C^2), Q is the magnitude of the charge, d is the distance between the charges, and r is the distance from the point to the midpoint of the dipole.
For example, if Q = 2 microcoulombs, d = 1 meter, and r = 0.5 meters, the electric field would be:
E = (9 x 10^9 Nm^2/C^2)(2 x 10^-6 C)(1 m) / (0.5^3 m^3) = 7.2 x 10^7 N/C
