Two particles, each of charge q and mass m, are held infixedpositions at a distance d from each other. A thirdidenticalparticle is then brought in from infinity and placed sothat aperfect equlateral triangle is formed by the particles, asdepictedin the diagram. Assume that the third particle was at restwhen itwas infinitely far away.
Given that q = 2.0 μC, m = 5.0 mg, and d = 2.0 cm:
a ) Determine the work which must be done by an externalagentto move the third particle into its position while the othertwoparticles remain in place.
b) Suppose that the three particles are suddenly released(fromrest) and allowed to move apart from each other, outtowardinfinity. Determine their final speeds when they areinfinitely faraway from each other.
Hint: Consider the symmetry of the situation to determinehowthe final speeds of the particles are related to eachother.
