Read the following and reference the pictures below:
The electric fields around multiple charges add vectorally. That is, if they have the same direction,
the effects add to each other (Figure A) and if they have opposite directions, the effects cancel each
other (Figure B). And if the directions are at angles to each other, their effects combine and act at a
new angle (Figure C).
1. Add these vectors and sketch the resulting vector:
Complete these sentences:
2. The space around a charged object is affected by the charged object. The space surrounding the
charged object is described as an
.
3. The
around multiple charges add vectorally.
4. A negative charge and a positive charge would
each other.
5. A negative charge and a negative charge would
each other.
6. The strength of the electric field surrounding a charged particle depends on the
of both particles and the
away from the particle.
7. If this positively charged object was allowed
to move freely but the negatively charged
ones could not, what would happen? Draw a
dashed line to show where you think the
positively charged object would go.
