1. Two electrons are 10^5 m apart. One electron is fixed on its
position. The other, originally at rest, is released. How fast is
the free electron moving when it is 10^ −3 m from the
fixed charge? Apply conservation of energy.
2. Two point charges, +400 uC and -2.00 uC are 0.55m apart. (a)
what is the potential energy of the pair? (b) If the positive
charge is fixed and the other is released from rest, how far from
each other should the charges be if the negative charge is moving
with a speed of 2.30 x 10^2 m/s? Let the mass of the moving charge
be 8.00 x 10^−6 kg.
