1. The problem statement, all variables and given/known data Two negative charges of -1.0 X 10^-6 C are placed in water and separated by a distance of 0.10 m. A positive charge of 1.0 x 10^-8 C is placed exactly midway between the two negative charges. Determine: a) the electric field( magnitude and direction) and electric potential i)at the position of the positive charge ii) either negative charge b) the electric force( magnitude and direction) experienced i) by the positive charge ii) by the negative charge 2. Relevant equations E=kq2/Kr2 F=eq1 F=kq1q2/Kr2 K is electric constant pertaining to material( in this case water) which is 80.4 W=kq2q1/Kr=Vq1 V=kq2/Kr 3. The attempt at a solution I don't know where to start.:S Any help will be appreciated.
