Two concentric conducting shells a and b are of radii R and 2R. A charge +q is centred at their center. Shell b is then earthed and a is given charge q. Find the charge on outer surfaces oboth shells.
Ans) THE charge on outer surface of A will be 2q and outer surface of B will be zero due to earthing charge on b will flow to earth.
Using cross belts cross the belt on the spool pulleys used in C 1 above and turn one of the pulleys. Note that they now turn in opposite directions.
Determine and plot for 5 keV to 100 MeV the fraction of the total cross section due to each of the four interaction processes for (a) hydrogen, (b) nitrogen, (c) aluminum,
A box is divided into two parts of equal volume via a partition. The box is thermally insulated from the surroundings. Consider that compartment 1 contains an ideal gas A at P 0 ,

Introduce concept about the carbon dioxide laser. A test target is vaporized and bursts within flame onto irradiation through a high power continuous wave carbon dioxide laser
what is atom
The mass of a string is 4.20 x 10 -3 kg, and it is stretched so the tension in it is 135 N. A transverse wave traveling on this string has a frequency of 260 Hz and a wavelength o
How Does a Cat Land on its Feet? The saying is in which cats always land on their feet. This animation describes how they do this.
Rutherford's alpha-scattering experiment recognized that the mass of atom is concentrated with small positively charged region at the centre which is known as 'nucleus'. Nuclei
