A charged sphere in static equilibrium is resting on a
horizontal surface. Directly above it is another charged sphere
(also in static equilibrium) that is hanging from a 9,000 N/m
spring. The 36 kg red sphere has more charge than the 49 kg green
sphere. The total charge magnitude on the spheres is 248 µC &
they have the same polarity. As a result the spring is stretched
0.02 m& the centers of the spheres are 0.66 m
apart. Determine the charge magnitude on each
sphere.

A
charged sphere in static equilibrium is resting on a horizontal
surface. Directly above it is another charged sphere (also in
static equilibrium) that is hanging from a 12 N/m spring. The 34 kg
red sphere has more charge than the 1 kg green sphere. The total
charge magnitude on the spheres is 26 µC & they have the same
polarity. As a result the spring is stretched 0.25 m & the
centers of the spheres are 0.32 m apart....

A charged sphere in static equilibrium is resting on a horizontal surface. Directly above it is another charged sphere (also in static equilibrium) that is hanging from a string. The 34 kg red sphere has more charge than the 31 kg green sphere. The total charge magnitude on the spheres is 65 µC & they have opposite polarity. As a result, the tension is 322 N & the centers of the spheres are 0.69 m apart. Determine the charge magnitude...
Two charged spheres on a frictionless horizontal surface are attached to opposite ends of a 750 N/m spring & are in static equilibrium. The 24 kg red sphere has more charge than the 9 kg green sphere. The total charge magnitude on the spheres is 59 μC & they have opposite polarity. As a result the spring is compressed 0.03 m & the centers of the spheres are 0.57 m apart. Determine the charge magnitude on each sphere.
Two charged spheres (A & B) are 6.1 m apart. The magnitude of charge on sphere A is 17 times smaller than the magnitude of charge on sphere B. If sphere A is exerting a 668 N electrostatic force on sphere B, how much electrostatic force is B exerting on A ?
T wo identical small charged spheres, each having equilibrium. The length L of each string is 0.150 m, and the angle is 5.000. Find the magnitude of the charge on each sphere. a mass of 3.00×1022 kg, hang in
1. Rocket observations show that dust particles in Earth's upper atmosphere are often electrically charged. a) Find the distance separating two dust particles (in m) if each has a charge of +e and the Coulomb force between them has magnitude 1.30 ✕ 10−14 N. b)Calculate the mass (in kg) of one of the dust particles if this Coulomb force would accelerate it at 2.60 ✕ 108 m/s2. (In the upper atmosphere, effects from other nearby charges typically result in a...
