A charge of #2 C# is at the origin. How much energy would be applied to or released from a # 1 C# charge if it is moved from # ( -2 , 1 ) # to #( -4 , 2) #?
Given two charges:
Find the energy required to move from
First let's list the key definition and principles we need to solve this problem:
That is a lot of energy, the reason is that a Coulomb is a huge charge. Typically you would have smaller charges and shorter distances. BTW I made an assumption that all distances are meters your question is silent on that...
The relevant principles are 20 Work formula and distance formula
Technically what we need is:
but by inspection all you need the linear separation
