The radiation pressure 1 ~m away from a 330 ~W electric bulb is

Options

  1. A1.25 10⁻⁷ P
  2. B8.75 10⁻⁸ P _ a
  3. C5.45 10⁻⁸ P _ a ^ a
  4. D8.50 10⁻⁷ P _ a ^ a

Correct answer

B. 8.75 10⁻⁸ P _ a

Step-by-step solution

I = P A = 330 4 1^2 =26.26 watt / m ^2 So, Radiation Pressure = I C = 26.26 3 10^8 =8.75 10⁻⁸ ~Pa
