Click For Summary
The acceleration due to gravity on the surface of the Earth is essentially constant, with minimal day-to-day variation. The discussion highlights that gravity does not change significantly, contrasting it with conditions on the moon. Participants clarify that the original post likely referred to a multiple-choice question regarding gravity. The overall consensus emphasizes the stability of Earth's gravitational force. Understanding this concept is crucial for physics-related studies.

I think that was his multiple-choice question.
 
Thread 'Correct statement about size of wire to produce larger extension'

Thread 'Correct statement about size of wire to produce larger extension'

The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
