If the voltage between 2 plates is 10 V and they are separated by 2 m, what is the electric field? A. 10 V/m B. 5 V/m C. 2 V/m D. 20 V/mWhat does it mean when there is a straight line on a current vs voltage graph?A. Current is proportional to the Voltage squared.B. Current and Voltage are not proportional.C. Current and Voltage are directly proportional.D. Current and Voltage are inversely proportional.

Answer :

1) We will have that:

[tex]E=\frac{kQ}{r^2}[/tex]

So:

[tex]E=5V/m[/tex]

2) We will have the following:

It would mean that:

Current and voltage are directly proportional.
