Two objects attract each other gravitationally with a force of 3.5 10-10 N when they are 0.33 m apart. Their total mass is 4.0 kg. Find their individual masses. larger mass kg ? smaller mass kg ?

Thats the thing, I have no idea where to begin. I know that us = 0.34 and acceleration = 0 which means Fnet = 0 but that's all.

Can anyone help? The coefficient of static friction between hard rubber and normal street pavement is about 0.34. On how steep a hill (maximum angle) can you leave a car parked?
