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?

A) 200 m/s
B) 350 m/s
C) 6600 m/s
D) 7.1 x 10⁴ m/s
E) 2.0 x 10⁵ m/s
