Electrostatics Part 3

A positive ion A and a negative ion B has charges 6.67×10−19C and 9.6×10−10C, and masses 19.2 ×10−27‌kg and 9×10−27‌kg respectively. At an instant, the ions are separated by a certain distance r. At that instant the ratio of the magnitudes of electrostatic force to gravitational force is P×10−23, where the value of P is ______ (Take ‌
