(a) A metallic bar has a mass 200 g at poles. Does it change when taken to equator?
(b) Does it's weight change when brought to equator? If yes, how?
(c) What would happen if there was no acceleration due to gravity?
(d) Differentiate between acceleration due to gravity and universal gravitational constant .
(e) Derive a relation between 'g' and ' G' .
Answers
Explanation:
a) Mass remains same through out the universe.so at poles and equator mass 200g will not change. as Radius at equator is more, g value decreases so weight at equator also decreases. ... Hence weight of the object at the Centre of earth will be zero.
b)Yes, you weigh less on the equator than at the North or South Pole, but the difference is small. Note that your body itself does not change. Rather it is the force of gravity and other forces that change as you approach the poles. These forces change right back when you return to your original latitude
c)If there was no acceleration due to gravity, all objects and bodies would float in the air. Like If we are in space. Nothing will be down to earth.
d) don't know
e) Hint: G is the force between two bodies of unit mass separated by distance r. ... g is the acceleration produced in a body falling under the action of gravitational pull of the earth. Here g is called acceleration due to gravity. Equation for g is F=mg and Equation for G is F=Gm1mr2.
