Expert Answer
Gravitational field between two body for net force zero is
where G is the gravitational constant and M is the mass of the earth 
is the charge in earth and m is the mass of the charge Q is the charge of the mass and it is negative.
is the charge in earth and m is the mass of the charge Q is the charge of the mass and it is negative.
since the charge is negative so direction of the field of the earth is opposite to that of the charge.
