Question

Three identical particles with the same charge *q* and
mass *m* are held at the corners of an equilateral triangle
with sides *d* as shown:

a) If all three particles are released simultaneously, what is their speed when they have traveled a large distance (effectively an infinite distance) from each other?

b) Suppose instead that the particles are released one at a time. The first one is released, and when it is at a large distance away the second one is released, and when that one is at a large distance away, the third one is finally released.

What are the final speeds of:

(1) the first released particle?

(2) the second released particle?

(3) the last particle?

Four identical particles (charge Q=1.6 nC, mass m = 4 g) are
placed at corners of a square of side b = 5.9 cm. What is the
electric potential energy of this system? (The electric potential
energy is zero when the particles are very far apart.)
The particles are now released from rest. What is the speed of
each particle when they are very far apart? (You may ignore
gravity.)

Three identical 50-kg balls are held at the corners of an
equilateral triangle, 30 cm on each side. If one of the balls is
released, what is the magnitude of its initial acceleration if the
only forces acting on it are the gravitational forces due to the
other two masses? (G = 6.67 × 10^-11 N · m^2/kg^2)

Three identical charged particles sit at the corners of an
equilateral triangle of side length 30 cm. Each particle has a
charge of 8.5μc. The charges Q1 and Q2 are positive and Q3 is
negative.

Two identical particles of charge 6 μμC and mass 3 μμg are
initially at rest and held 3 cm apart. How fast will the particles
move when they are allowed to repel and separate to very large
(essentially infinite) distance? Now suppose that the two particles
have the same charges from the previous problem, but their masses
are different. One particle has mass 3 μμg as before, but the other
one is heavier, with a mass of 30 μμg. Their...

Two particles which have the same magnitude charge but opposite
sign are held r = 7 nm apart. Particle I is then released
while Particle II is held steady; the released particle has a mass
of 8.72 × 10-23 kg. Particle I's speed is 110 km/s when
it is 0.74r away from Particle II.
1. What is the magnitude of the charge on one
of the particles?
2. If the particles are still initially held 7 nm apart but
both...

(a) Two particles which have the same magnitude charge but
opposite sign are held 9.00 nm apart. Particle I is then released
while Particle II is held steady; the released particle has a mass
of 1.02 10-22 kg. Particle I's speed is 108 km/s when it is 4.5 nm
away from Particle II. What is the magnitude of the charge on one
of the particles?

Three charged particles are placed at the corners of an
