Questions & Step-by-Step Solutions
A dipole consists of two equal and opposite charges separated by a distance of 0.1m. What is the dipole moment if each charge is 1μC?
Correct Answer: 1 × 10^-7 C m
Step 1: Understand what a dipole is. A dipole consists of two equal and opposite charges.
Step 2: Identify the values given in the question. The charge (q) is 1μC (microcoulomb) and the distance (d) between the charges is 0.1m.
Step 3: Convert the charge from microcoulombs to coulombs. 1μC = 1 × 10^-6 C.
Step 4: Use the formula for dipole moment, which is p = q * d.
Step 5: Substitute the values into the formula: p = (1 × 10^-6 C) * (0.1 m).
Step 6: Calculate the dipole moment: p = 1 × 10^-7 C m.
Dipole Moment – The dipole moment is a measure of the separation of positive and negative charges in a system, calculated as the product of the charge and the distance between the charges.
