A question off my lab

  1. Feb 2, 2006 #1

    I'm having troubles with this problem off my lab and I'm wondering if any of you guys could help me with this one.

    Suppose you have fixed charge of -60 x 10^-9C at point X. Points A and B are at distances of 0.04 meters and 0.14 meters from X, respectively.

    Calculate the speed of point B of a proton that was moving to the right at point A with a speed of 12 x 10^5 m/s.

    edit: fixed the problem up, was a typo.

    >fixed charge of -60j x 10^-9C at point X

    What does that mean? How can charge be an imaginary number? -60jnC?
