Homework Statement
In a certain region of space, the electric field along the x-axis is given by:
E = 1.2x - 3.06, where E is in N/C and x is in meters.
If you set the electric potential equal to zero at (4.39 m,0), find the electric potential, in V, at the point (7.22 m,0).
Homework Equations
V = - ∫E * dl
The Attempt at a Solution
[/B]
V = - ∫ (1.2X-3.06) dx
⇒ V = - [1.2X2/2 - 3.06X]02.83
⇒V=3.85 → which is http://www.dabur.com/odomos/images/wrong_sign.jpg ...any suggestions?
