# {{ params.vars.title }}
Two parallel conducting plates ${{params.L}} \textrm{ cm}$ on a side are given equal and opposite charges of magnitude ${{params.q}}\times 10^{ {{params.p}} } \textrm{ C}$.

The plates are ${{params.d}}\rm\ mm$ apart.

## Part 1

What is the magnitude of the electric field at the centre of the region between the plates?

### Answer Section

## Part 2

What is the direction of the electric field at the centre of the region between the plates?

### Answer Section

- {{ params.part2.ans1.value }}
- {{ params.part2.ans2.value }}
- {{ params.part2.ans3.value }}
