Which direction the normal is supposed to be :S?

i can only help u with the second one cuz right now i am extremely busy :(....

okay as for the normal line my teacher said use one set square ... place the bottom of it on the surface  where it is EXACTLY PERPENDICULAR to the surface and the draw the line ...
 
 a tip from me :P ....after u do this use a protractor and measure the angle from the normal line udrew to the surface ...if it's exactly 90 then ur drawing is 100 % correct ..but if it's not it means u gotta draw it agian until u get it right .

hope i helped

my teacher didn't draw line AD that way but he a bit stretched it out ..in other words,  he drew a line from point A and went around the voltmeter till he reached point D...
