An electric dipole consists of charges +2e and -Ze separated by 10 nm. It is placed in a space above a horizontal charged sheet with a surface charge density of o: 20pC/m2. a) Using Gauss' law, determine, what is the direction and magnitude of the Electric field generated by the sheet b) What is the torque exerted on a dipole by the Electric field of the sheet if the orientation of the dipole with respect to the positive x direction (regular right handed cartesian coordinate system) is 130 ? Make sure to draw the dipole vector on the diagram with the sheet below (Use following constants and definitions : e = -1.6 x 10-19 C, k: 8.99 x109 N m2/C2 , so = 8.854 x10-12 CZINmZ, u (mikro) =106, n (nanno) = 10-9) sheet
