two point charges are 10.0 cm apart and have chargeso of 2.0 uC (micro)and -2 uC, respectively. What is the magnitude of the electric field at the midpoint between the two charges?

i think the answr is zero..

but i don't understand how to get to it...can you please show me in clear steps how to solve for this...please. i don't understand the way my teacher showed it., pleae show me in steps with explanation. thank you a lot

  • physics -

    Definitely not zero. The E contribution from each charge points in the same direction, not in opposite.

    Isn't E=kq/r^2, so you double it, and point it toward the negative charge?

  • physics -

    but i checked and it does point in the opposite direction

    the charges are differnect signs.....

    i'm confused!
