A Light Source Radiates $60.0 \mathrm {~W}$ Of Single-Wavelength Sinusoidal Light Uniformly in All Directions

Multiple Choice

A light source radiates $60.0 \mathrm {~W}$ of single-wavelength sinusoidal light uniformly in all directions. What is the amplitude of the electric field of this light at a distance of $0.400 \mathrm {~m}$ from the bulb? $\left( \varepsilon _ { 0 } = \right.$ $\left. 8.85 \times 10 ^ { - 12 } \mathrm { C } ^ { 2 } / \mathrm { N } \cdot \mathrm { m } ^ { 2 } , \mu _ { 0 } = 4 \pi \times 10 ^ { - 7 } \mathrm {~T} \cdot \mathrm { m } / \mathrm { A } , c = 3.00 \times 10 ^ { 8 } \mathrm {~m} / \mathrm { s } \right)$

B) $212 \mathrm {~N} / \mathrm { C }$
C) $162 \mathrm {~N} / \mathrm { C }$
D) $150 \mathrm {~N} / \mathrm { C }$
E) $82.1 \mathrm {~N} / \mathrm { C }$
