Electric field strenght of a loop given maximum flux

Click For Summary

Homework Help Overview

The problem involves calculating the electric field strength of a circular loop given the maximum electric flux through it. The loop has a diameter of 29 cm, and the flux is measured at 7.2e5 Nm²/C.

Discussion Character

  • Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • The original poster attempts to use the relationship between electric flux and electric field strength but questions the correctness of their calculation. Participants inquire about the area of the loop and whether it is equivalent to that of a circle.

Discussion Status

Participants are exploring the relationship between the area of the loop and the calculation of electric field strength. Some guidance has been offered regarding the area formula, and there is a clarification that a circular loop and a circle are considered the same in this context.

Contextual Notes

There is a focus on ensuring the correct application of the area formula for the circular loop, and the original poster expresses uncertainty about their initial calculation.

Homework Statement


a 29 cm diameter circular loop is rotated in a uniform electric field until the position of maximum electric flux is found. the flux is measured to be 7.2e5 Nm^2/C
what is the electric field strength in units N/C?


Homework Equations


flux = EA


The Attempt at a Solution


7.2e5 Nm^2/C = E * (.29m/2)^2
E = 34244946.4923

apparently it's not the right answer though...

thanks!

What is the area of the circle?
 
the area of a circle is pi*r^2...but this is a loop...or are they the same thing?

Circular loop and circle is the same.
 
awesome! thank you.
