Hi I attempted this questions on gravitation.
Written below, my solving is at the very bottom.
It is asking about gravitational field strengths with the
following.
Earth - 9.8 = g, 6400x10^3 = R

12.2 s Use the information below to calculate (a) the Earth's gravitational field strength at the Moon, (b) the distance from the Earth's surface to the point between the Earth and Moon where the overall gravitational field strength due to Earth and Moon is zero. The Earth-Moon distance is 3.8 X 108 m. 1 Surface gravitational field strength/Nkg-1 Radius/km Earth 9.8 6400 Moon 1.6 1600
