Two electrons each of mass 9.1* 10^-31 kg area at a distance of 10 ^-10 m .calculate the gravitational force of attraction

we have the following formula for gravitational force

F = Gme2 / r2

[as m = M = me]

here,

G = 6.67 x 10-11 Nm2/kg2

me = 9.1 x 10-31 kg

r =10-10 m

so,

F = [6.67 x 10-11 x (9.1 x 10-31)2] / (10-10)2

thus,

F = 552.3427 x 10-53 N
