So I am supposed to find the distance from the moon where the force on a particle from the Earth and sun is equal.
I get this expression (earth-moon distance is 400 000km):
yMm/(r^2) = yMm / (400000km-r)^2
But from that I get r=200 000km and the answer should be 40 000km...
whats wrong with the expression?
thanks
