Answer the following statement(s) true (T) or false (F)
1. The units of the electric field 
are N/C. We can alternatively say the field has units of V/m.
2. A single particle can have potential energy.
3. Even if we define the potential to be zero at infinity, the potential created by a charge distribution can be negative at another point.
4. Consider a point P midway between two particles, one with charge -q and one with charge q. The electric field vector at point P is zero.
