Question

Consider the arrangement of three small charged spheres, each of mass 14 g, shown in the figure. The spheres have equal charges of 65 nC and are positioned on the vertices of an equilateral triangle, with side length 37 cm.

Answer #1

If these spheres are released at precisely the same time, how fast, in meters per second, will they be moving when they are infinitely far away form each other?

Solution.

The type of mechanical energy that solely depends on the state of motion of the body is kinetic energy of that body. This energy cannot be developed for a body that is at rest.

Two
identical small, charged spheres, each having a mass of 30 g, hang
in equilibrium as shown in the figure. The length Lof each string
is 0.7 m, and the angle theta is 50. Find the magnitude of the
charge on each sphere in (nC).(ke=9*109N.m2/C2)

The figure below shows three small, positively charged spheres
at three corners of a rectangle. The particle at upper left has a
charge q1 = 6.00 nC, the one at the lower left
has a charge of q2 = 7.00 nC, and the one at
lower right has a charge q3 = 3.00 nC. The
rectangle's horizontal side has length x = 5.50 cm and its
vertical side has length y = 3.50 cm.

In the figure three identical conducting spheres form an
equilateral triangle of side length d = 26.4 cm. The sphere radii
are much smaller than d and the sphere charges are qA = -3.65 nC,
qB = -4.20 nC, and qC = +9.17 nC. (a) What is the magnitude of the
electrostatic force between spheres A and C? The following steps
are taken: A and B are connected by a thin wire and then
disconnected; B is grounded by the...

Three identical small metal spheres form an equilateral triangle
of side length d = 3.5 cm. Initially, q1 = +2.0 nC, q2 = +6.0 nC,
and q3 = ?8.0 nC. Sphere 2 is first moved to touch sphere 1, then
moved again to touch sphere 3, and finally returned to the original
position. What now is the magnitude of the electrostatic force
exerted on sphere 1 by the other two spheres (in N)?
The answer was: 1.0*10^4 N

Three uniform spheres are located at the corners of an
equilateral triangle. Each side of the triangle has a length of
1.43 m. Two of the spheres have a mass of 3.49 kg each. The third
sphere (mass unknown) is released from rest. Considering only the
gravitational forces that the spheres exert on each other, what is
the magnitude of the initial acceleration of the third sphere?

Three uniform spheres are located at the corners of an
equilateral triangle. Each side of the triangle has a length of
1.24 m. Two of the spheres have a mass of 2.59 kg each. The third
sphere (mass unknown) is released from rest. Considering only the
gravitational forces that the spheres exert on each other, what is
the magnitude of the initial acceleration of the third sphere?

Three uniform spheres are located at the corners of an
equilateral triangle. Each side of the triangle has a length of
1.12 m. Two of the spheres have a mass of 2.64 kg each. The third
sphere (mass unknown) is released from rest. Considering only the
gravitational forces that the spheres exert on each other, what is
the magnitude of the initial acceleration of the third sphere?

Three uniform spheres are located at the corners of an
equilateral triangle. Each side of the triangle has a length of
