Q: What is the electric potential due to a dipole at a point along the axial line at a distance 'r' from the center of the dipole?
Solution: The potential V = k * p / r, where p is the dipole moment.
Steps: 6
Step 1: Understand what a dipole is. A dipole consists of two equal and opposite charges separated by a small distance.
Step 2: Know the dipole moment (p). It is defined as the product of the charge (q) and the distance (d) between the charges: p = q * d.
Step 3: Identify the point where you want to find the electric potential. In this case, it is along the axial line of the dipole at a distance 'r' from the center.
Step 4: Recall the formula for electric potential (V) due to a dipole at a point along the axial line: V = k * p / r.
Step 5: Understand the variables in the formula: 'k' is a constant (Coulomb's constant), 'p' is the dipole moment, and 'r' is the distance from the dipole center to the point.
Step 6: Substitute the values of 'p' and 'r' into the formula to calculate the electric potential at that point.
