A plane electromagnetic wave of electric and magnetic fields $E_0$ and $B_0$ respectively incidents on a surface. If the total energy transferred to the surface in a time of $t$ is $U$, then the magnitude of the total momentum delivered to the surface for complete absorption is
- A$\frac{U E_0}{B_0}$
- B$\frac{U B_0}{E_0}$
- C$\frac{U_0}{E_0 B_0}$
- D$\frac{U B_0}{E_0^2}$
✓ Correct answer: B
