Va Va 0 x In a two dimensional box, the potential is specied on the boundary as shown in the picture. You can use separation ofyariahle technique to solve the Laplace's equation, such that (x, y} = X(m}Y(y) and 1 sixes) 1 daYly} =0. 111:} do\" Yly) y\" Now you can choose both terms are constant. Which one you will assign to a negative constant? C) The one with Yiy] function. 0 Both have to be 0 in this case to satisfy the Laplace's equation. 0 The one with XIX] function. 0 It does not matter which one
