 find the total charge enclosed inside a   volume of 1.5×10^(−9)  located at the origin  if D=e^(−x) sin(y)a_x ^� −(e^(−x) cos(y))a_y ^� +2za^� z C/m^2

pv=▽.D^→   pv=−e^(−x) sin(y)+e^(−x) sin(y)+2=2  Q_(enc) =∫_v pv . dv  Q_(enc) =pv∫dv  Q_(enc) =pv . v=1.5×10^(−9) ×2=3 nC
pv=.Dpv=exsin(y)+exsin(y)+2=2Qenc=vpv.dvQenc=pvdvQenc=pv.v=1.5×109×2=3nC
