Answer 1

Answer:The acceleration due to gravity at the moon's surface is 1.67 ms^(-2). If the radius of the moon is 1.74 xx 10^(6) m, calculate the mass of the moon. ... Now, g=1.67ms-2,R=1.74×106m ... Mass of the moon, M=1.67×(1.74×106)26.67×10-11kg ... C

Step-by-step explanation:

Answer 2

Answer:

As, g=

GM

R2

 

orM=

gR2

G

 

 

This relation is true not only to the earth but for any heavenly body which is assumed to be spherical  

Now, g=1.67ms-2,R=1.74×106m  

G=6.67×10-11Nm-2kg-2  

∴ Mass of the moon, M=

1.67×(1.74×106)2

6.67×10-11

 

kg  

=7.58×1022kg.
