Four neutral objects are sketched below, in black and white. There are positive and negative electric charges inside these objects, and at least some of those
charges can move around.
Now suppose a negative charge comes close to these objects, as shown in the sketch.
Shade the objects red anywhere you expect them to become more negatively charged, and shade the objects blue anywhere you expect them to become
more positively charged.
