If the total energy transferred to a surface in time $t$ is $6.48\times {10}^5 \mathrm{J}$, then the magnitude of the total momentum delivered to this surface for complete absorption will be :

• A

  $2.46\times {10}^{-3} \mathrm{kg} \mathrm{m} {\mathrm{s}}^{-1}$
• Correct answer
  B

  $2.16\times {10}^{-3} \mathrm{kg} \mathrm{m} {\mathrm{s}}^{-1}$
• C

  $1.58\times {10}^{-3} \mathrm{kg} \mathrm{m} {\mathrm{s}}^{-1}$
• D

  $4.32\times {10}^{-3} \mathrm{kg} \mathrm{m} {\mathrm{s}}^{-1}$

Hence, the correct answer is option: 'B'.
