Answer the following statement(s) true (T) or false (F)
1. Consider the electric field shown below:
This is a physically possible static electric field (that is, we can calculate a well-defined potential difference between any two points in this field).
2. Consider the electric field shown below:
(This hypothetical field is uniform to the left of the boundary shown and zero to the right of that boundary.) This is a physically possible static electric field (that is, we can calculate a well-defined potential difference between any two points in this field)
