A point charge +Q is fixed at a height H above the ground. Directly below this charge is a small ball with a charge -q and a massm. When the ball is at a height h above the ground, the net force(gravitational plus electrical) acting on it is zero. Is this a stableequilibrium for the object? Explain.

A charged puck (with charge -5.0 x 10^-4 C and mass 2.0 kg) is placed on a table in a region with a uniform electric field. The puck accelerates at 5.0 m/s^2 to the right. If the friction force which the table exerts on the puck is 2.0 N (left), what is the electric field (magnitude and direction)?
Why is the following situation impossible? Two identical dust particles of mass 1μg are floating in empty space, far from any external sources of large gravitational or electric fields, and at rest with respect to each other. Both particles carry electric charges that are identical in magnitude and sign. The gravitational and electric forces between the particles happen to have the same magnitude, so each particle experiences zero net force and the distance between the particles remains constant.
Three charges of −7 nC, −4 nC and 0.5 nC are situated at P(3, π/4, π/4), Q(0, 5, π, π/4) and S(−1, π/6, 3π/4),respectively. Calculate the electric force on the −4 nC charge at point Q. Is this force attractive or repulsive?
A +7.00 µC particle is located at x = 0.0 cm, and a –9.0 μC particle is located at x = 40.0 cm. Where must a positive test charge be placed along the x–axis so that the net electric force on it is zero? Hint: In a FBD, place the test charge left of x = 0 cm, in between the two source charges, and right of x = 40 cm. Sketch the direction and relative magnitude of the net force at each location and determine where it might be possible for the net force to be zero. Then set the magnitudes of the forces equal to each other.
