Homework Statement
How much work (in J) is required to bring a charge of 2 microC from the point {2*6.8,-7,2*1.1}cm via the point {10,20,1}cm to the point {-3*6.8,3.4,-3*1.1}cm, in a medium with relative permittivity of 3.7, near a line charge along x=6.8 cm, z=1.1 cm, with charge density +329 microC/m? (Hint: what is the sign of the answer? Note that * simply means scalar multiplication)
Homework Equations
V= integral (E.dl) yields V=(charge/length)ln(R)/(2pi(relative permittivity)
W=Q(deltaV)
The Attempt at a Solution
I've tried to calculate the voltage at the first point but get a huge number assuming the line of point charges is acting as a cylindrical charge at the first point then same for middle point and last then using W=Q(deltaV).
No success.
Could someone please point me in the right direction.
Do I even need to consider the middle point?
Thank you.
