Potential difference that needs to be mantained

[alicia113]

Calculate the potential difference that would have to be maintained across the plates of a parallel plate apparatus, if the plates were 1.2cm spat, to create an elecric field strength of 1.5x10^4 N/C.


i have no idea how to do this! someone please help

I think you just need to use E=V/d (rearrange to get V) :)
