The electric field of a plane polarizedelectromagnetic wave in free space at timet = 0 is given by an expression E^{\to} (x , y) = 10 j^{\^} cos [(6x + 8z)] The magnetic field B^{\to} (x , z , t) is given by : (cis the velocity of light) [10 Jan 2019 Shift 2]

Correct Answer is : 1c(6^k−8^i) cos [(6x + 8z - 10ct)]

1/c (6k^{\^}+8i^{\^}) cos [(6x - 8z + 10ct)]

1/c (6k^{\^}-8i^{\^}) cos [(6x + 8z - 10ct)]

1/c (6k^{\^}+8i^{\^}) cos [(6x + 8z - 10ct)]

1/c (6k^{\^}-8i^{\^}) cos [(6x + 8z + 10ct)]
