The electric potential in a certain region as a function of the x-coordinate (in meters) is 4 - 6x + 7x^2. Find the x-component of the electric field at the point x=2

Question

anonymous · Answer

Is this supposed to be the partial derivative of the potential function? I.e. gradients

anonymous · Answer

yup

anonymous · Answer

posiibly yes

anonymous · Answer

Do you divide this partial by the distance or just the derivative evaluated at the position x = 2?

anonymous · Answer

just do the derivative at x =2

anonymous · Answer

Remember its the negative of the derivative
$$E_x = -\frac{\delta V}{\delta x}$$
