Please help me
The way it works here is
-you post a question
-say how far you've got with it or what equations you know that might apply
-say where you are stuck or at least show you have made some effort
This will ensure you get some help.

Do you know the equation F = GMm/r^2?
I got this far:
GMm/ r^2 =0
Original post by sheepshap
I got this far:
GMm/ r^2 =0
GMm/ r^2 =0
What is the value of r at the point where the force is zero.
Which mass, the M or the 4kg, are you measuring it from?
