The Problem:
The electric potential in a certain region is
V = αx2y2+βz2(x2-γ)+δy3z
where α = 5 V/m4, β = 4.5 V/m4, γ =6.8 m2, and δ = 7.1 V/m4.
What is the y component of the electric field Ey at (1.3 m, −3 m, 4.4 m)?
Answer in units of V/m
My Attempt:
I took the partial derivative with respect to y and got
Ey = 10x2y + 4.5z2(x2-6.8) + 21.3y2z
(But I think I may have done that wrong...)
I then plugged in my values for x, y, and z, and got 347.5968 as my answer, which was wrong. Any help would be appreciated! :)
