Explanation:
(i) (a) g on the moon is given by
g =
g
/
6
=
9.8
/
6
= 1.63m/s2
(b) Mass of the person on the moon
=
110.84
/
1.63
= 68 kg
(c) Weight of person on the earth = mg
= 68 x 9.8
= 666.4 N-m2/kg2
(ii) Weight of a person on the earth will be
w = GMm÷R/2
where, M = mass of the earth
R = radius of the earth
m = mass of person
and G = 6.67 x 10-11 N-m2/kg2
