Radiation of intensity `1 W//m^(2)` are striking on a metal plate. The pressure on the plate isA. `0.66 xx 10^(-8) N//m^(2)`B. `0.25 N//m^(2)`C. `2 N//m^(2)`D. `4 N//m^(2)` |
|
Answer» Correct Answer - A As metal is reflecting surface and for reflecting surface radiation pressure, `p_(r) = (2S)/(c) = (2 xx 1)/(3 xx 10^(8)) = 0.667 xx 10^(-8) Nm^(-2)` |
