Final answer:
To calculate the work done to bring three electrons from a great distance apart to within 2.0×10⁻¹⁰ m from one another at the corners of an equilateral triangle, we can use Coulomb's Law and the equation for work. The force between the electrons can be calculated and then multiplied by the distance to find the work done.
Step-by-step explanation:
To calculate the work done to bring three electrons from a great distance apart to within 2.0×10⁻¹⁰ m from one another at the corners of an equilateral triangle, we can use the equation:
Work = Force x Distance
The force between two electrons can be calculated using Coulomb's Law:
Force = (k * q1 * q2) / r^2
where k is the electrostatic constant, q1 and q2 are the charges of the electrons, and r is the distance between them.
Since the electrons are at the corners of an equilateral triangle, the distance between them is equal to the side length of the triangle. Using the given value of 2.0×10⁻¹⁰ m, we can calculate the force and then multiply it by the distance to find the work done.
