Question

The function V = e^xsin y + z does not satisfy Laplace equation. State True/False.

(a) True

(b) False

This question was posed to me in my homework.

My doubt is from Poisson and Laplace Equation in section Electrostatic Boundary Value Problem of Electromagnetic Theory

Answer 1

Right answer is (b) False

The explanation: Grad (V) = e^xsin y i + e^x cos y j + k. Div(Grad(V)) = e^xsin y – e^xsin y + 0= 0.Thus Laplacian equation Div(Grad(V)) = 0 is true.
