Introduction
When dealing with electric charges, understanding the potential difference between two points is crucial in various fields, including physics and engineering. The potential difference, also known as voltage, is a measure of the electric potential energy per unit charge between two points. In this article, we will explore the concept of potential difference and calculate the potential difference 18 m from a 0.00000022 C charge.
Understanding Electric Potential
Electric potential, also known as voltage, is a measure of the electric potential energy per unit charge between two points. It is typically denoted by the symbol V and is measured in volts (V). The electric potential at a point in space is defined as the work required to move a unit charge from infinity to that point.
Coulomb's Law and Electric Potential
Coulomb's Law describes the force between two point charges. However, it can also be used to calculate the electric potential at a point due to a charge. The electric potential due to a point charge is given by the equation:
V = k * q / r
where:
- V is the electric potential at a point due to the charge
- k is Coulomb's constant (approximately 9 x 10^9 N m^2 C^-2)
- q is the magnitude of the charge
- r is the distance between the charge and the point where the potential is being measured
Calculating the Potential Difference
To calculate the potential difference 18 m from a 0.00000022 C charge, we can use the equation above. We are given the charge (q = 0.00000022 C) and the distance (r = 18 m). We can plug these values into the equation to find the electric potential at the point 18 m from the charge.
Step 1: Plug in the values
V = k * q / r V = (9 x 10^9 N m^2 C^-2) * (0.00000022 C) / (18 m)
Step 2: Simplify the equation
V = (9 x 10^9) * (0.00000022) / (18) V = (1.98 x 10^6) / (18) V = 1.1 x 10^4 V
Conclusion
The potential difference 18 m from a 0.00000022 C charge is approximately 1.1 x 10^4 V. This means that if we were to place a charge of 1 C at a point 18 m from the given charge, it would require 1.1 x 10^4 J of work to move it to that point.
