How do you calculate and compare the gravitational and electrical forces between an electron and a proton separated by 10 to the negative 10 m.
Is the answer:
m x a = (4p2r/t2)= 10  30 x 4 x1021= 4x10

Lauren,
Is the answer F subscript elec F subscript grav = (8.22 x 10 subscript 8) (3.63 x 10 subscript 47) = 2.26 x 10 subscript 39
