Given a vector field, show flux across all paths is the same.

SUMMARY

The discussion focuses on demonstrating that the flux of the vector field F = 3x²i - y³j across any two curves C1 and C2 from the x-axis to the y-axis is identical. The divergence of the field is calculated as divF = Ny + Mx, which equals zero, indicating that the vector field is conservative. The solution suggests applying Green's Theorem to establish that the flux remains constant across different paths.

PREREQUISITES
  • Understanding of vector fields and their properties
  • Familiarity with Green's Theorem
  • Knowledge of divergence and curl in vector calculus

Homework Statement


Given the vector field F=3x^2i-y^3j, show that the flux over any two curves C1 and C2 going from the x to the y axes are the same.

Homework Equations


Flux = int(F dot n ds) = int(Mdy - Ndx)
divF = Ny + Mx


The Attempt at a Solution


We can show the divergence of the field is zero => Ny = -3y^2 and Mx = 3y^2
so divf = Ny + Mx = 0... does this help in any way? Thanks
