Given, mass of charges, m1‌=m2=1g
‌=10−3‌kg
r‌=1m
∴ Gravitational force between them,
FG‌=‌

Gm1m2

r2

‌=‌

6.67×10−11×10−3×10−3

‌[∴G=6.67×10−11N−m2∕kg2]
‌=6.67×10−17N
Again, charge on m1 and m2,
q1=q2=1‌ femto coulomb ‌=10−15C
∴ Electrostatic force between the both charges,
Fe‌=‌

=9×10−21N
∴ Clearly FG≫Fc
Hence, gravitational force is dominant force.
