## Homework Statement

You're 1.5 m from a charge distribution whose size is much less than 1 m.

You measure an electric field strength of 282 N/C. You move to a distance of

2.0 m, and the field strength becomes 119 N/C.

Hint: Don't try to calculate the charge. Instead determine how the field

decreases with distance and from that, infer the charge.

## Homework Equations

## The Attempt at a Solution

All I was taught by the prof was that I need to break charge distribution

into elements of dq and then integrate over the distance. However, the

question does not necessarily state the distance of the distribution, which is

why I think the question gives two instances of field measurements, i'm not

sure how to approach the question from here. Hope that I can get a good

lead on how to solve this question. Thanks.
