Question

You connect two parallel plates to a 100 V difference in potential (electrostatic voltage source). The left plate is connected to ground of electrostatic voltage source. Plate 2 is connected to +30V electrostatic voltage source


b) Now, suppose now you disconnect the electrostatic voltage source and then slowly separate the plates.

i.What will happen to ?V, the difference in potential between the plates, and E, the magnitude of the elelctric field between the plates?
?V remains the same, E decreases

both ?V and E remain the same

?V increases, E decreases

?V remains the same, E increases

?V decreases, E increases

both ?V and E increase

?V increases, E remains the same

both ?V and E decrease

?V decreases, E remains the same

** other answers to this question say it is V increases, E remains the same
BUT webassign says it is wrong!

Please help!!

Explanation / Answer

V remains same but E decreases
