Homework Statement
Find the net force given a point charge and the value of the electric field.
Homework Equations
FE = εq
ε= (5.6*10^4)
q=(-1.2 * 10^-5)
The Attempt at a Solution
FE = εq
FE = (5.6*10^4)(-1.2 * 10^-5)
FE = 0.672 N
Seriously. I am posting this question.
Here's the answer the book gave:
FE = εq
FE = (5.6*10^4)(-1.2 * 10^-5)
FE = (6.7*10^4) N
It does this again on the answer to the next question, increasing the magnitude by 10^5.
Everything I know tells me I'm right but I need to be sure I'm not doing something very wrong. I don't know why this text is still in circulation if its riddled with this many errors.
