Question

An astronaut carried a pot containing soil weighing 120 N from the earth to the
surface of moon. He kept it there and just before return journey from moon to
earth he weighed the soil there on the surface of moon and found that it was
only 20N.
a) What causes the difference in the weight on earth and
moon?
b) Give the relationship between weight of an object on moon and
earth.
c) Using the above data calculate the mass of the soil on
Earth?
OR
A force of 10 N acts upon a body whose weight is 19.6 N. What is the mass of
the body and how much is its acceleration?

Answer 1

Answer:

Acceleration due to gravity at poles is slightly greater than that at equator. Weight of gold at equator We=mg' But as g > g' ⟹Wp>We Hence the weight of gold is slightly less at equator.
