Question: 
In a certain region of space the electric potential can be described by the equation 
Note: the V after the expression is the units, volts. 
part 1) 
yz 
What is the change in potential energy of a system when moving an electron trom 2.79i + 4.77 j + 9.83k m to 3.07i + 10.97j + 14.74k m in this potentiaP 
part 2)
