552.3427×10^(-43) How to solve with process?  I was finding Force of gravitation between two electrons which masses 9.1×10^(-31)kg and both are at 1 fermi distance. And i ended up stucking here. Idk how to get the correct ans. Please help!!

Expert Answer
Gravitational attractive Force F  between two masses m1 and m2 that are separated by a distance d is given as
 
begin mathsize 14px style F space equals space G space cross times fraction numerator m subscript 1 space m subscript 2 over denominator d squared end fraction end style
where G = 6.67 × 10-11 N m2 kg-2 is gravitational constant
 
Hence if two electrons each has mass m = 9.1 × 10-31 kg are separated by a fermi distance 1 Fermi = 10-15 m ,
 
then garvitational force F is given as
 
F = ( 6.67 × 10-11 × 9.1 × 10-31 × 9.1 × 10-31 ) / 10-30 = 552.3427 × 10-43 N
