An electric dipole consists of two equal and opposite charged particles of mass 1.2 g and charge 3.7 μC separated by 1.7 mm. What is the escape speed of the positive charge - that is, how much speed would you have to give it so it would escape the other charge? 200 m/s 350 m/s 6600 m/s 7.1×104 m/s 2.0×105 m/s
