Solution
As we know a body's weight is the product of its mass and acceleration acting on it i.e
W
=
m
a
given,
m
=
20
k
g
here acceleration (a) would be
g
=
10
m
/
s
²
{because on Earth a body experiences acceleration and due to gravity (g)}
so, weight of the body on Earth is
W
=
20
×
10
=
200
k
g
as we know,
weight on moon
=
1
6
weight on earth
so weight on moon
=
200
6
=
33.33
