Two particles with the same mass, 70.0 g, are released from rest in space with an initial distance of 0.85 m between them. Particle A has charge 14.5 μC while particle B has charge 62.0 μC. What is the kinetic energy (in J) of particle B at the instant when the particles are 2.60 m apart? Round your answer to 2 decimal places.

Particle 1 has a mass of m1 = 3.30 × 10-6 kg, while particle 2 has a mass of m2 = 6.30 × 10-6 kg. Each has the same electric charge. These particles are initially held at rest, and the two-particle system has an initial electric potential energy of 0.140 J. Suddenly, the particles are released and fly apart because of the repulsive electric force that acts on each one (see the figure). The effects of the gravitational force are...

Two particles each have a mass of 5.6 x 10-4 kg. One has a charge of +5.4 x 10-6 C, and the other has a charge of -5.4 x 10-6 C. They are initially held at rest at a distance of 0.72 m apart. Both are then released and accelerate toward each other. How fast is each particle moving when the separation between them is one-third its initial value?
