Questions & Step-by-Step Solutions
The electric field due to a dipole at a point along the axial line is given by which formula? (2023)
Step 1: Understand what a dipole is. A dipole consists of two equal and opposite charges separated by a small distance.
Step 2: Identify the point where you want to calculate the electric field. In this case, it's along the axial line of the dipole.
Step 3: Recall the formula for the electric field due to a dipole at a point along the axial line. The formula is E = (1/4πε₀) * (2p) / r³.
Step 4: Break down the formula: 'E' is the electric field, 'p' is the dipole moment (which is the product of charge and distance between charges), 'r' is the distance from the center of the dipole to the point where you're measuring the field, and 'ε₀' is the permittivity of free space.
Step 5: Remember that the factor of (1/4πε₀) is a constant that helps in calculating the electric field in a vacuum.
