Questions
When a body is taken from poles to equator on the earth, its weight :
a
increases
b
decreases
c
remains the same
d
increases at south pole and decreases at north pole
detailed solution
Correct option is B
Earth's gravitational attraction and hence weight of an object decreases at equator compared to the poles as the equator is situated at a greater distance from the centre of the earth compared to the poles g=GMr2 .Also due to spin of earth about its own geometrical axis , the object placed on the surface of earth at the equator experiences centrifugal force, which reduces the weight of the object .Talk to our academic expert!
