(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

U = k(x^2 + y^2) What is the force exerted on the particle?

2. Relevant equations

F = -(¶U/¶x ihat +¶U/¶y jhat +¶U/¶z khat) <--couldnt get the del symbol right

determining force from potential energy

3. The attempt at a solution

F = -¶/¶x[k(x^2+y^2)]ihat - ¶/¶y[k(x^2 +y^2)]jhat

=-[2kx + Y^2]ihat - [kx^2 + 2ky]jhat

Im new to calculus, and im pretty sure that im not doing the derivative of this right...any help would be greatly appreciated.
