Question

A positive ion A and a negative ion B has charges 6.67 10^ -19 C and 9.6 10^ -10 C, and masses 19.2 10^ -27 kg and 9 10^ -27 kg 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^ -13 , where the value of P is _____. (Take 1 4 _0 = 9 10^9 Nm²C⁻¹ and universal gravitational constant as 6.67 10^ -11 Nm²kg⁻²)
