Example 6 : Find the value of 'g' on the surface of moon if an object of given mass having radius negligible to that of moon, is placed on it. Mass of moon, M = 7.4 x 10pawer22 kg Radius of moon, R = 1.75 x 10 pawer6 n Universal Gravitational Constant, G = 6.67 * 10power-11
Nm² kg-2
Answers
Explanation:
On the surface of the moon, the distance to the center of mass is the same as the radius: r=1.74×10

m=17,40,000 m. The acceleration due to gravity on the surface of the moon can be found using the formula:
g=
