can you walk me through this problem

At what distance from teh Earth will a spacecraft on the way to the Moon esperience zero net force due to these two bodies because the EArth and Mon pull with equal and opposite forces?

mass of earth = m1 = 5.98 E 24 kg
mass of moon = m2 = 7.36 E 22 kg
radius moon to earth = 3.84 E 8 m = r1 + r2
r1 = radius satalite to earth
r2 = radius satalite to moon
