Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

Question

I need help with a,b,c cause I am having trouble with this problem and my professor won't help.

Problem 3: The identical small spheres shown in Fig.3 are charged to
+100 nC and -100 nC. They hang as shown in an E = 105 N/C electric
field. What is the mass of each sphere?
a) In Fig. 3, draw the vectors that represent all the forces acting on
charge 1 (you should have 4 forces in total). Compute the magnitudes of
the electric forces acting on charge 1 (when computing the force exerted
on charge 1 by charge 2, you need to use the distance between the two
charges, which can be deduced from the geometry of the problem).

b) For the charge 1 to stay in equilibrium, all forces acting on it have to balance each other. Which
condition does this impose on the ratio between the total electric force acting on the charge and the
gravitational force, given the inclination angle of the string? Use this condition to find the mass of sphere 1.
c) Draw the vectors that represent all the forces acting on charge 2. Why is the system of charges
symmetric with respect to the vertical line, even though the electric field E points to the left?
