Change in gravitational field strength

Click For Summary

Homework Help Overview

The discussion revolves around a physics problem concerning the change in gravitational field strength between sea level and the summit of Mont Blanc, which is 4807 m high. The problem involves understanding gravitational forces and the relevant equations, particularly in the context of introductory physics coursework.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants express uncertainty about how to begin solving the problem and question the relevant equations related to gravitational force. Some seek clarification on how to set up the problem properly.

Discussion Status

The conversation is ongoing, with participants sharing their confusion and seeking guidance on how to approach the problem. There is an emphasis on understanding the setup rather than providing direct answers, and some participants have offered resources to aid in comprehension.

Contextual Notes

Participants note the challenge of the problem in relation to their introductory course level and the format of the online course, which may contribute to their difficulties in grasping the concepts involved.

Homework Statement


The tallest spot on Earth is Mt. Everest. But another well-known mountain is the Mont Blanc, European Alps, which is 4807 m above sea level. If the radius of the Earth to sea level is 6367 km, how much does the gravitational field strength change between the sea level value at that location (9.826 N/kg) and the top of the Mont Blanc?




The Attempt at a Solution



I don't even know how to begin. :-(

What is the equation for the force of gravity, in terms of the mass of the Earth, the mass of whatever you're weighing, and the distance between the two centers of mass? It has a big "G" constant in it as well...
 
I have no idea. I am supposed to be in an introductory course and it doesn't seem to be that way. On top of that it's an online course.
 
Thank you! But, I'm still confused. How do I set it up? Once I get it setup I can solve it.

Nope. You need to do the work, leslie. We don't do your homework for you. You wouldn't be learning if we showed you the relevant equations and set everything up for you.

Re-read the question, and read the link that I provided, and think through how you can use that equation for this problem. Show us your work and we can try to help more.
