Homework Help Overview

The discussion revolves around calculating the magnitude and direction of resultant forces based on given values. The problem appears to involve forces F1 and F2, with participants sharing their calculations and seeking clarification on their results.

Discussion Character

  • Exploratory, Assumption checking, Mathematical reasoning

Approaches and Questions Raised

  • Participants present their calculations for forces F1 and F2, with some expressing uncertainty about their values. There are attempts to verify calculations and question the correctness of the results. Others suggest re-evaluating the calculations and provide alternative values for the forces.

Discussion Status

The discussion is ongoing, with participants sharing different values for the forces and their resultant calculations. Some guidance has been offered regarding re-checking calculations, but there is no explicit consensus on the correct values or approach yet.

Contextual Notes

Participants mention specific calculations and methods used, including gravitational force equations, but there are indications of potential mistakes in the initial values provided. The context suggests a focus on understanding the calculations rather than arriving at a final answer.

I attached problem.

I got F1 = 2.7x10-8
and F2 = 8.3x10-9

sqrt(f1^2 +f2^2) = 2.818x10^-8

theta was inverse tan of f1/f2. got 72.8

please help :(

I don't get these forces. Perhaps you should attach you calculations.
sqrt(f1^2 +f2^2) = 2.818x10^-8

theta was inverse tan of f1/f2. got 72.8

please help :(

Re-check your calculations for F1 and F2.
 
I think I know what I did...dumb mistake.

Did you get:
f1=2.04E-7
f2=1.762E-7

NEW magnitude= 2.69E-7
NEW theta=49
 
and I was using F=G(7.30)(7.30)/(0.132)^2 for F1 and F2 just subbed in 0.427.

Thanks for your help.

F2 is still incorrect.
 
Yeah I don't know what I did there. I got it now though. magnitude:2.05E-7 and direction of 85 degrees.

Thank you!
