Charge densityrequired toproduce afield. Alayer of charge fills the space between x = -a andx = +a.The layer has a charge density p(x). The electric field intensity everywhere inside the charge distribution is given by E(x) = x&3, where K is a given constant. Assume the layer is in free space.
(a) Calculate the charge density p(x).
(b) What can you say about the charge density for x > 0 and for x O?
(c) How does the charge density vary in they and z directions?
