A point charge is a = 1.5 m below the end of a continuously charged rod with charge Q = 5 ?C.
a) Write an expression for the differential element of the y component of the Electric Field at P in terms of the charge density and position y of piece of charge dq along the y-axis.
b) Calculate the y component of the Electric Field at P in N/C.
c) Calculate the x component of the Electric Field at P in N/C.
d) As b increases, the magnitude of the electric field at P decreases, why?
