1.要有什麼條件才可以令電場彎左?
2.Van de graaff 產生什麼charge?係咪負電?有d人話唔係,但Notes寫係!
3.F3 Physics 點溫?由electrostatics--->electric field----->electric current------>electrical energy and voltage----->resistance.
4.The arrows of the field lines show the direction of the force acting on a +ve
charge at that point.點解唔係負電???
5.The denser the field lines,the stronger is the electric field.唔明呢句講?野
幫我解,唔該
F3 Physics

✔ 最佳答案
f3學E&M咁勁??我f5先學....通常f3教heat/wave/mech1.未學
2.係靜電 有可能正有可能負 視乎個generator
3.我f3唔係學呢d呢...我宜家溫E&M係不斷操past paper
或者你f4f5讀science既話,你早d買練習都冇壞
我推介aristo 你識做哂連考會考都唔會有問題，因為真係好難
4.field line由正去負
你放粒正電係field line度就show到正同正係repel
5.d線愈密field愈強
