Final answer:
The electric field strength 1.5 cm from an electric dipole, on the axis of the dipole, is approximately 3.57 x 10⁴ N/C.
Step-by-step explanation:
The electric field strength 1.5 cm from an electric dipole, on the axis of the dipole, can be calculated using the formula:
E = (p / 4πε₀r³)
where E is the electric field strength, p is the dipole moment, ε₀ is the permittivity of free space, and r is the distance from the dipole.
Let's say the dipole moment is 5 C·m and the distance is 0.015 m (converted from 1.5 cm). Plugging these values into the formula:
E = (5 C·m / (4π(8.854 x 10^-12 N·m²/C²)(0.015 m)³))
Simplifying the equation gives us:
E ≈ 3.57 x 10⁴ N/C
