Radiations of intensity (0.5 Wm ⁻² ) are striking a metal plate, the pressure on the plate is
Options
- A(0.166 10⁻⁸ Nm ⁻² )
- B(0.332 10⁻⁸ Nm ⁻² )
- C(0.111 10⁻⁸ Nm ⁻² )
- 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 )
