Homework Statement
A) Calculate the work performed by an external agent to move a charge of -0.59x10-12 C from `i' to `b'.
B) Calculate the magnitude of the electric field at `k'
Homework Equations
W = q∆V
Where ∆V is the potential difference between the two potential lines each point
lies on
E = -∆V/∆L
The Attempt at a Solution
A) I know the work equation is charge x the change in V but I am not sure how to interpret the Equipotential lines in order to get change in V.
B) I know the equation is E = -∆V/∆L but I am not sure how to calculate both those variables from the graph.
The real question I have is how to interpret this graph to get ∆V and ∆L? I know that an Equipotential contour graph shows the plain perpendicular to the e-filed thus making Volts zero at any place there isn't a point charge.
