QUESTION:

Problem 23P

(II) How much work must be done to bring three electrons from a great distance apart to 1.0 X

10-10 m from one another (at the corners of an equilateral triangle)?

ANSWER:

Step-by-step solution

Step 1 of 2

We are going to find how much work is needed to bring three electrons which are infinitely apart from each other, to the corners of an equilateral triangle of one side 1,0x10-10m.

When the three electrons are very far away from each other, we can say the distance between them is infinite. If the distances between the electrons are infinite, the charges are not in interaction with each other so potential energy of the system is zero.
