Options

  1. A(0.166 10⁻⁸ Nm ⁻² )
  2. B(0.332 10⁻⁸ Nm ⁻² )
  3. C(0.111 10⁻⁸ Nm ⁻² )
  4. D(0.083 10⁻⁸ Nm ⁻² )

Correct answer

A. (0.166 10⁻⁸ Nm ⁻² )

Step-by-step solution

Intensity of radiation, (I=0.5 Wm ⁻² ) Pressure on the plate due to radiation is given by (p= I c = 0.5 3 10^8 =0.166 10⁻⁸ Nm ⁻² )
