a) Find the magnitude of the
electrostatic force between 2
negative charges seperated by a
distance of 1augustro.
b)what is the magnitude of gravit'l
force between the negetive charges
(electro)?
c) determine the ratio of the gravt'l
force and electrostatic force.
((Help with even the formulae!))

forceelectric=kqq/a^2

I wonder what the magnitude of the two negative charges is?

forcgravity= GMM/a^2 YOu did not specify the masses of the charges.

forceelectric/forcemagnetic= k/G * qq/MM

You still haven't told us what an augustro is

1agustron is equivalent to 10''-10m (10 rest power -10)
