Question

the acceleration due to gravity on the surface of the moon is 1.62 ms-2 . the radius of moon is 1740 km . find the mass of the moon​

Answer 1

Answer:

Explanation:Given:-

Radius of moon = 1740Km = 1740000m

acceleration due to gravity = 1.62m/s-2

g = acceleration due to gravity

G = gravitational constant(6.67 * 10^-11)

m = mass

r = radius

g = G*(m1m2/r^2)

m = (g * r^2)/G

m = (1.62 * (1740000)^2)/(6.67 * 10^-11)

m = 7.34767309 × 10^22 Kg
