In a region of free space the electric field at some instant of time is E^{\to} = (40i^{\^}+16j^{\^}-32k^{\^}) V/m and the magnetic field is B^{\to} = (0.1i^{\^}+0.04j^{\^}+0.145k^{\^}) T . The poynting vector for these fields in W\/m^2 is

Correct Answer is : 1074π [3.6^i−9.0^j]

10^7/{2\pi} [3.6i^{\^}-9.0j^{\^}]

10^7/{4\pi} [3.6i^{\^}-9.0j^{\^}]

10^7/{8\pi} [3.6i^{\^}-9.0j^{\^}]
