Charge per unit length for a charged ring

  1. Apr 3, 2015 #1
    1. The problem statement, all variables and given/known data
    If you have a ring of charge, is it valid to say lambda = Q/L, or is it lambda = dQ/dL?

    2. Relevant equations


    3. The attempt at a solution

    dq/dl which works out to be q/l if the charge is uniformly distributed.
