Problem

On a square grid with

1\,\text{cm}

spacing, the electric field vector at (

0\,\text{cm}

,

0\,\text{cm}

) is

30\,\text{N/C}

directed due north, and at (

0\,\text{cm}

,

2\,\text{cm}

) it is

50\,\text{N/C}

directed due north. Determine the approximate electric field (magnitude and direction) at the point (

0\,\text{cm}

,

1\,\text{cm}

).
