Asked by Joanna
Consider the electric field created by a very long charged line of negative linear charge density -2.50 nC/m.
A small positive point charge of 7 mC moves from a distance of 9 cm to a distance of 17 cm.
How much work is done by the electric field?

Find the E field due to the long wire (Use Gauss law) at some distance r.
Work= E(9)q-E(17)q
Work= E(9)q-E(17)q
