## Homework Statement

I've been set an assignment and I'm struggling with one question in particular:

## Homework Equations

'Use the following data and plot the graphs for a point charge'

'Plot graph of E against r^2. Interpret the graph to describe electric field strength and electric potential.'

The figures provided are r(m)=Distance from a point charge, and, V(V)=Voltage at a distance 'r' from a point charge.

## The Attempt at a Solution

More than anything I'm just really stuck how to find E from the figures provided? Any help would be greatly appreciated! Thanks
