An infinite dielectric sheet having charge density sigma has a holeof radius R in it. An electrom is released from point P on the axis of the hole at a distance sqrt(3)R from the center. Find the speed with which it crosses the plane of the sheet.

it was observed that the power radiated becames `(256)/(81)P_0`. The shift in wavelength corresponding to the maximum energy will be On changing the temperature of the black body Power radiated by a black body is `P_0` and the wavelength corresponding to maximum energy is around `lamda_0`
