A 1.0 µC test charge travels along an equipotential line a distance of 0.250 cm between two parallel chcarged plates with a field strength of 200.0 N/C. What is the change in voltage?

Question

anonymous · Answer

0 V , -100 V , +100 V , or +1000 V

michele_laino · Answer

It is zero Volts, since if the charge moves along a equipotential line, that no potential energy change occurs during that motion, then no voltage change occurs

michele_laino · Answer

oops.. along an equipotential line, then no...

anonymous · Answer

ok! so it is 0 V?

michele_laino · Answer

yes!

anonymous · Answer

yay! thanks!!

rvc · Answer

equipotential means same potential everywhere
if the difference of potential is 0 then no charge exists @Michele_Laino right?

michele_laino · Answer

more precisely, if the differential of potential is zero, then the electric field is not able to do any work on a specific charge @rvc

rvc · Answer

oh okay

michele_laino · Answer

electric charges can exist independent by any external field
