## anonymous one year ago For the electric field shown, which of the following statements describes an increase in voltage? A. A positive charge moves along an equipotential line. B. A positive charge crosses an equipotential line toward the source charge. C. A negative charge crosses an equipotential line toward the source charge. D. You cannot tell from the information given.

ok!

4. Michele_Laino

the electric voltage is given by the subsequent formula: $V\left( r \right) = K\frac{Q}{r}$

5. anonymous

ok! what do we plug in?

6. Michele_Laino

where r is the subsequent distance: |dw:1433443640459:dw|

7. Michele_Laino

in order to increase the potential, we have: 1) decrese the distance r, if the other charge is positive 2) increase the distance r if the other charge is negative

8. Michele_Laino

decrease*

ohh okay!! so then our solution is choice B? :/

10. Michele_Laino

that's right!
