1.A small stationary 0.005 kg plastic ball is sits in
equilibrium at a distance 0.4 mm above the bottom plate and
has a small charge q. The forces acting on the small ball are
the force of gravity and the electric field.
What is the charge on the ball
2. How would the acceleration of an electron between the plates
compare to the acceleration of a proton between the plates?
acceleration of the electron would be one thousand eight
hundred thirty times as large, and in the opposite direction.
acceleration of the electron would be the same magnitude, but in
the opposite direction
acceleration of the electron would be negligibly small while the
proton would accelerate downward at 9.8 m/s2m/s​2​​
acceleration of the electron would be twice as large and in the
opposite direction
acceleration of the electron would be one hundred times as
large, and in the opposite direction.
acceleration of the electron would be the square root of 2 times
as large and in the opposite direction.
