Charge `q_(1) = +6.0n C` is on y-axis at `y = + 3cm` and charge `q_(2) = -6.0 n C` is on y-axis at `y = -3 cm`. Calculate force on a test charge `q_(0) = 2 n C` placed on X-axis at `x = 4cm`.

A point charge q_1 = 4.00 nC is placed at the origin, and a second point charge q_2 = -3.00 nC , placed on the x-axis at x = + 20.0 cm. A third point charge q_3 = 2.00 nC is placed on the X-axis between q_1, and q_2 . (Take as zero the potential energy of the three charges when they are infinitely far apart). (a) What is the potential energy of the system of the three charges if q_3 is placed at x= + 10.0 cm? (b) Where should q_3 be placed to make the potential energy of the system equal to zero?

In Fig. a, particle 1 (of charge q_(1) ) and particle 2 (of charge q_(2) ) are fixed in place on an x axis, 8.00 cm apart. Particle 3 (of charge q_(3)=+8.00xx10^(-19)C ) is to be placed on the line between particles 1 and 2 so that they produce a net electrostatic force F_("net")=2F_(0) on it Figure b gives the x component of that force versus the coordinate x at which particle 3 is placed.
