If the total energy transferred to a surface in time t is 6 . 48 × 10 5 J , then the magnitude of the total momentum delivered to this surface for complete absorption will be :

Options

  1. A2 . 46 × 10 - 3 kg m s - 1
  2. B2 . 16 × 10 - 3 kg m s - 1
  3. C1 . 58 × 10 - 3 kg m s - 1
  4. D4 . 32 × 10 - 3 kg m s - 1

Correct answer

B. 2 . 16 × 10 - 3 kg m s - 1

Step-by-step solution

As we know, p = E c , where c is velocity of light. Therefore, p = 6 . 48 × 10 5 3 × 10 8 = 2 . 16 × 10 - 3 kg m s - 1
