           \[\left( \frac{q}{{{\varepsilon }_{0}}} \right)\] normal to surface

B)            \[\left( \frac{q}{2{{\varepsilon }_{0}}} \right)\] normal to surface

C)            \[\left( \frac{q}{{{\varepsilon }_{0}}} \right)\]  tangential to surface

D)            \[\left( \frac{q}{2{{\varepsilon }_{0}}} \right)\]  tangential to surface
