Radiation of intensity 1 W//m^(2) are striking on a metal plate. The pressure on the plate is

Monochromatic rays of intensity I are falling on a metal plate of surface area A placed on a rough horizontal surface at certainn angle theta as shown in figure. Choose correct statement (s) based on above information a) There is a value of θ for which plate will not move however high the intensity of radiation is b) Plate will not move if plate if perfectly reflecting irrespective of the value of intensity c) If rays are falling perpendiculars to surface plate will not have d) none of these

A black totally absorbing piece of carboard of area A=2.0 cm^(2) intercepts light with an intensity of 10 W//m^(2) from a camera strobe light . What radiation pressure is produced on the cardboard by the light ?

The separation between the plates of a parallel-plate capacitor is 0.500 cm and its plate area is 100 cm^2. A 0.400cm thick metal plate is inserted into the gap with its faces parallel to the plates .Show that the capacitance of the assombly is independent of the position of the metal plate within the gap and find its value.
