Solve the all parts of given question:
Question: The electric potential in a region of space is V=300Vm/(x2+y2)(1/2), where x and y are in meters.
Part A: What is the strength of the electric field at (x,y)=(3.0m,1.5m)?
Part B: What is the direction of the electric field at (x,y)=(3.0m,1.5m)? Give the direction as an angle ccw from the positive x-axis.
Show all work, use additional paper if necessary.
