Hello. This is my first time here, so let me know if I'm doing anything wrong "posting-wise."
The electric potential in a region of space is V= (260 x^2 - 180 y^2) V, where x and y are in meters.
What is the strength of the electric field at (2.00 m, 3.00 m) ?
x = 2.00 m
y = 3.00 m
E = -grad(V)
E = -grad(V) = -(520(x) - 360(y)) = -(-40) = 40
I feel really stupid because it's not the right answer... What am I doing wrong? Thanks in advance!
