Two particles each have a mass of 63 103 kg One has a charge

Two particles each have a mass of 6.3 10-3 kg. One has a charge of +5.1 10-6 C, and the other has a charge of -5.1 10-6 C. They are initially held at rest at a distance of 0.76 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?

Two particles each have a mass of 6.3 10-3 kg. One has a charge of +4.9 10-6 C, and the other has a charge of -4.9 10-6 C. They are initially held at rest at a distance of 0.82 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?

Answer

applying conservation of energy,

initial potential energy = final potential energy + kinetic energy

K*Q*Q / r     =    K*Q*Q /(r/3) + 1/2 m * v^2   +1/2 m*v^2

=> v =9.09 m/s
