What Is the Magnitude of the Electric Field $2.8 \mathrm {~cm}$

What is the magnitude of the electric field $2.8 \mathrm {~cm}$ from a tiny object that carries an excess charge of $- 16 \mathrm { nC } ? \left( k = 1 / 4 \pi \varepsilon _ { 0 } = 9.0 \times 10 ^ { 9 } \mathrm {~N} \cdot \mathrm { m } ^ { 2 } / \mathrm { C } ^ { 2 } \right)$

A) $5100 \mathrm {~N} / \mathrm { C }$
B) $180,000 \mathrm {~N} / \mathrm { C }$
C) $1.8 \times 10 ^ { 14 } \mathrm {~N} / \mathrm { C }$
D) $- 5100 \mathrm {~N} / \mathrm { C }$
E) $- 180,000 \mathrm {~N} / \mathrm { C }$
