Question on voltage and electric field

[santi69r]

Homework Statement

what voltage should be put across a pair of parallel metal plates 10.cm apart if the electric field between them is to be 1.0V?

so far i have read through the part in the textbook but am unable to understand since the questions are unlike this.probably is really easy though.
so far just wondering if this is right
E =V/d
E is the charge between the two plates
V is the voltage and
d is the distance between the plates

V = e x d
1 x 10
V = 10 V
Thanks

Hmmm... The electric field is 1.0 V? Are you sure about the units there? Also, your units of distance is in cm and not the proper SI unit when you plugged it in your formula.

yeah thats the question its only 1.0 Vm-1.
so your saying it should be in si not actually sure.
would like to know if that is the right formula

Well you said yourseld that the electric field is V/m, and then you do E*d (V/m * cm). So the units won't come out right. You need to convert the cm to m. And that is the correct formula.
