Answer #1

In the figure particle 1 of charge q1 = 1.08
μC and particle 2 of charge q2 = -2.94 μC, are
held at separation L = 9.1 cm on an x axis. If
particle 3 of unknown charge q3 is to be
located such that the net electrostatic force on it from particles
1 and 2 is zero, what must be the (a)x
and (b)y coordinates of particle 3?

In the figure particle 1 of charge q1 = 0.91
μC and particle 2 of charge q2 = -3.09 μC, are
held at separation L = 10.5 cm on an x axis. If
particle 3 of unknown charge q3 is to be
located such that the net electrostatic force on it from particles
1 and 2 is zero, what must be the (a)x
and (b)y coordinates of particle 3?

In the figure particle 1 of charge q1 = 0.94 μC and particle 2
of charge q2 = -2.91 μC, are held at separation L = 10.6 cm on an x
axis. If particle 3 of unknown charge q3 is to be located such that
the net electrostatic force on it from particles 1 and 2 is zero,
what must be the (a)x and (b)y coordinates of particle 3?

Chapter 21, Problem 019 In the figure particle 1 of charge +q

In the figure particles 1 and 2 are fixed in place on an x axis,
at a separation of L = 6.50 cm. Their charges are q1 = +e and q2 =
-64e. Particle 3 with charge q3 = +5e is to be placed on the line
between particles 1 and 2, so that they produce a net electrostatic
force F3 net on it. (a) At what coordinate should particle 3 be
placed to minimize the magnitude of that force?...

Three particles are fixed on an x axis. Particle 1 of
charge q1 is at x = -a and
particle 2 of charge q2 is at x =
+a. If their net electrostatic force on particle 3 of
charge Q is to be zero, what must be the ratio
q1/q2 when particle 3 is at
(a) x = +0.334a and
(b) x = +2.09a?
