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 × 10⁴⁵, where the value of 10P is
(Take 1/4πε₀ = 9 × 10⁹ Nm²C⁻² and universal gravitational constant as 6.67 × 10⁻¹¹ Nm²kg⁻²)
