Three point charges lie in a straight line along the
y-axis. A charge of q1 = -9.70 µC is
at y = 6.80 m, and a charge of q2 =
-8.30 µC is at y = -4.20 m. The net electric force on the
third point charge is zero. Where is this charge located?
y = m
An alpha particle (charge = +2.0e) is sent at high
speed toward a gold nucleus (charge = +79e). What is the
electric force acting on the alpha particle when the alpha particle
is 3.7 ✕ 10-14 m from the gold nucleus?
