Question

Two small metal spheres are 26.0 cm apart. The spheres have
equal amounts of negative charge and repel each other with a force
of 0.036 N. What is the charge on each sphere?

A +2.5 nC point charge is 3.3 cm away from a -3.1 nC point
charge.

What are the magnitude and direction of the acceleration of an
electron at a point where the electric field has magnitude 6600 N/C
and is directed due north?

Answer #1

Two uncharged metal spheres, spaced 25.0cm apart, have a
capacitance of 26.0 pF. How much work would it take to move 16.0 nC
of charge from one sphere to the other?
W=?

A total charge of 7.50 × 10−6 C is distributed on two
different small metal spheres. When the spheres are 6.30 cm apart,
they each feel a repulsive force of 21.4 N.

5. Two identical metal spheres are placed 15.0 cm apart. A
charge of 6.00 µC is placed on one sphere while a charge of −2.00
µC is placed upon the other. What is the force on each sphere? If
the two spheres are brought together and touched and then separated
to their original separation, what will be the force on each
sphere?

There are two identical, positively charged conducting spheres
fixed in space. The spheres are 32.0 cm apart (center to center)
and repel each other with an electrostatic force of F1 = 0.0750 N.
Then, a thin conducting wire connects the spheres, redistributing
the charge on each sphere. When the wire is removed the spheres
still repel but with a force of F2 = 0.100 N. Using this
information, find the initial charge on each sphere, q1 and q2 if
initially...

There are two identical, positively charged conducting spheres
fixed in space. The spheres are 47.8 cm apart (center to center)
and repel each other with an electrostatic force of F1 = 0.0720 N.
Then, a thin conducting wire connects the spheres, redistributing
the charge on each sphere. When the wire is removed the spheres
still repel but with a force of F2 = 0.115 N. Using this
information, find the initial charge on each sphere, q1 and q2 if
initially...

Two identical conducting small spheres are placed with their

Two metal spheres each have a radius of 10.0 cm. The centers of
the two spheres are 54.1 cm apart. The spheres are initially
neutral, but a charge Q is transferred from one sphere to the
other, creating a potential difference between the spheres of 107
V. A proton is released from rest at the surface of the positively
charged sphere and travels to the negatively charged sphere.
(a) What is the proton's kinetic energy just as it strikes the...

Two conducting spheres are separated by 1.5 cm. One sphere is
charged such that its total charge is 32 nC. The other sphere is
electrically neutral (has no net charge).
A) Is there an apparent charge distribution on the neutral
sphere due to the charged sphere? Qualitatively answer this using
diagrams and terminology such as charge by induction, charge by
conduction, dipole, octopole, etc.
B) Imagine the spheres were allowed to touch for a brief moment
and then separated back...
