A Positron has the same mass, but opposite charge to an electron. A Positron and electron are orbiting around each other separated by 1μm, in a stable circular orbit about their centre of mass, as a result of electrostatic attraction. Calculate the period

State Coulomb's law:F=(1/4πE 0 ) (qQ/d 2 )Since the distance separating the charges is twice the radius of the orbit relabel d to 2r and the charges are equal and opposite:F= -(1/16πƐ 0 ) (q/r) 2 Notice that...
