    I found this question in a phy6 edexcel paper:
    Outline briefly how does a Van de Graaff generator can accelerate electrons to a very high energies

    And i Have the mark scheme and it says:
    (Electron gun at) high voltage/potential/p.d. (1)
    Relative to earth/below earth [Accept anode for earth] (1)
    Exerts force on/repels electrons (1)
    (because of large) charge/electrons on hemisphere/dome/belt (1) Max 3

    But can someone explain it to me in full sentences,and if possible can write more about Van de Graaff ?
    Thx in advance :redface: :ahee:

    It's much easier for you to read this than it is for me to explain it.
