What is Stoke's theorem?
The circulation of a vector field $A$ around a closed path $I$ is equal to the surface integral of the curl of $A$ over the open surface bounded by $L$, provided $A$ and $\Delta XA$ are continuous on $S$.
Applicability of Stoke's theorem
Yes, Stoke's theorem is applicable only if $A$ and $\Delta XA$ are continuous on $S$.
Relationship between circulation and surface integral
The circulation of a vector field $A$ is equal to the surface integral of the curl of $A$.
Study Notes
Divergence of a Vector Field
- The divergence of the vector field P is not equal to 2XYZ + X, as the expression lacks a differential operator.
Divergence in Cartesian Coordinates
- The divergence of the vector field P in Cartesian coordinates is given by ∇⋅P = (∂P_x/∂x) + (∂P_y/∂y) + (∂P_z/∂z).
Divergence in Cylindrical Coordinates
- The divergence of the vector field P in cylindrical coordinates is given by ∇⋅P = (1/r) (∂(rP_r)/∂r) + (1/r) (∂P_θ/∂θ) + (∂P_z/∂z).
Stoke's Theorem
- Stoke's theorem relates the circulation of a vector field around a closed curve to the surface integral of the curl of that vector field.
Applicability of Stoke's Theorem
- Stoke's theorem is applicable only if the vector field A and its first partial derivatives are continuous on the surface S and its boundary.
Relationship between Circulation and Surface Integral
- The circulation of a vector field A around a closed curve is equal to the surface integral of the curl of A, i.e., ∯A⋅dl = ∬ (∇×A) ⋅dS.
