## Homework Statement

A strip of magic tape 1 cm by 20 cm is charged uniformly with a net charge of -45 nC. The tape is stuck onto a table. Find the electric field 3.5 cm above the centerline of the tape, at the right hand edge. You may need to write a computer program to evaluate the field.

## Homework Equations

## The Attempt at a Solution

Basically, I think i can find the magnitude of the electric force by finding the electric field of a line of charge and integrating over the length of the tape, but I don't know how to split this up into components.

Any help would be appreciated...
