A 10m long wire of resistance 20 ohm is connected in series with a battery of emf 6v and a resistance of 10 ohm. Then how we can find the potential gradient along the wire in volt per meter?

This looks like homework so, If someone provides an answer, how will you know if it's reasonable?
You should attempt the answer for us and I'm sure many will comment...
