I found: $10, 000 \frac{J}{sec}$ $10,000J/sec$

Explanation:

Well, analyzing the units you should have:
$10N/cancel(C)*100m*10cancel(C)/(sec)=10,000Nm/(sec)=10,000J/sec$ that is in units of work per second.

From what I understand in your wire (of $100m$ length) you have a fileld or force per coulomb that moves 10 coulombs every seconds along it....I think.

10kilowatts

Explanation:

Determination of voltage:

Electric Field Intensity=Force/charge

But Voltage=Electric Field Intensity x length

Therefore

Voltage=(Force/charge )x length

$V=F/QxxL$

$V=10xx100$

$V=1000$ volts

Determination of current:

$I=Q/t$

Where Q=charge ; t=time.

$I=10$ Amperes

Determination of power:

$P=VI$

P=power=work done/sec

$P=10xx1000$

$P=10000$ watts
