hi every1, i'm a bit confused for this question. I know it seems simple(really, its just finding the gradient - or is it?) but i can't seem to get the correct answer. The answer in BOB is : 6.6 x 10^-34 J s. I keep getting : 4.125 x 10^-15 eV  :(.
Thanks, methodsboy

I get a gradient of eVs.

You can convert eV to J by multiplying by the fundamental charge , since
