Electromagnetic Waves: JEE Main 2021 Physics question

A radiation is emitted by 1000W bulb and it generates an electric field and magnetic field at P, placed at a distance of 2m. The efficiency of the bulb is 1.25%. The value of peak electric field at P is x $\times$ 10^$-$1 V/m. Value of x is ___________. (Rounded off to the nearest integer) [Take ${\varepsilon _0} = 8.85 \times {10^{ - 12}}$ C²N^$-$1 m^$-$2, c = $3 \times {10^8}$ ms^$-$1]
