Homework Statement
The electric potential in a region of space is
, where x and y are in meters. What is the strength of the electric field at (x,y)=(2.1m,2.7m)?
The electric force is in V/m.
Homework Equations
E = -grad(V)
E = -dV/ds
The Attempt at a Solution
I know that i have to find the partial derivatives of the x and the y but I am not sure on how to get the answer from the equation given. I was thinking of making the square root into the exponential of 1/2 and then raising that to -1 to get ride of the fraction and then taking the derivatives of that but i keep getting the wrong answer. Anybody have suggestions of help they can give me please. Thanks.
