Hi , am a computer science student , am newbie at physics , and am train to learn but no help , though i took a course in [physics 1] before 3 yrs and i cant remember anything, and now i am taking physics 2 , i took so far , electric fields , Gauss law ,Electric potential , capacitance . book >> [Physics for Scientists and Engineers, 6th Edn. (R.A.Serway) ]

Does it requires me to go back to physics 1 to understand those ?

and if anyone can help me or solve these questions(i have no clue about them) i would be appreciated .

You could get by without out knowing mechanics fairly well. If your learning Electricity and magnetism you could get by with out knowing mechanics.
