    What are the dimensions for electric charge? What are the dimensions for the electric field? Dimensions for potential? Dimentions for capacitance? They are a, b c question and I have to choose one

    for electrica charge I can choose from: a) LQ^-1 b (Q^-2)/M c LT^-2 d Q e QT^-1

    ahh what exactly do you mean by dimension ? What i know is that charge is the product of current and time

    I am translating from spanish. So I dont know if that is the way it must be translated into english. But I think we have to do is try to compose the electric charge by using elemental units like m, s, Kg, etc.

    Ok since charge = current * time , so the unit for current is Ampere whereas the unit for time is seconds, so the unit for charge comes out to be As -> if that is what you are asking for :S

    In the above options that you have given what do L and Q indicate ?

    I think they means length and charge.

    I think the correct answer is d) Q

    If you are asking for the unit of charge then that will be Q

    Can you give the options for the second question

    dimensions for electric field: a) LTQ b) (L^2)(T^-1)(Q^-1) c) ML(T^-2)(Q^-2) d) ML(T^-2)(Q^-2) e) ML(Q-1)

    So, L= Length T = Temperature Q = Charge

    I think the answer is e) coz E=F/Q

    As far as i remember force = mass * g

    Ok. Lets try dimensions for potential energy a) (L^2)(T^2)(Q^2) b) M(L^2)(T^-2)(Q^-1) c) ML(T^-1)(Q^-1) d) MQL(T^-1) e) L(T^-1)(Q^-2)

    Umm well let's see , potential energy = force * length

    which means mass * acceleration * length

  29. anonymous

    which further means mass * length^2 *time^-2

    According to me the answer would be ML^2T^-2 , but this answer isn't in the options you gave
