Itâ€™s called the curl vector. Itâ€™s not in jee syllabus per se but you can look up the notation in determinant form on the internet. Itâ€™s fairly straightforward.

One thing about curlâ€¦

You can remember that for a force F if curlĂ—F is 0 it means that the force is conservative.

Mujhe vo determinant kabhi yaad nahi rahta tha. Actually usse agar simplify karega to it leads to:

*Partial derivative of force wrt x= partial derivative of force wrt y = partial derivative of force wrt z*

Yaha tak sahi hai. It works if force is 2 dimensional.

3 dimensional force ke liye this is wrongâ€¦ 3d ke liye curlĂ—F hi karna padta hai.

Ohh, i didnâ€™t know that

But JEE me 3 dimensional force aata bhi nahi tha WEP questions me

Yes.

Thank you all.

Great explanations. Understood.
