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.
DISPLACEMENT: The change in the position of a body from its starting position to its final position is known as displacement. It is denoted by d ?.
Assumptions: Kinetic Energy=KE, Potential Energy=PE m=mass of the skateboarder=55 kg, Velocity v=1.80m/s So ,Initial Energy(KE) of the skateboarder=mv 2 /2 = 0.5* 55 * (1.8)^
The Moon is a satellite of the Earth. The Moon takes one full revolution around the Earth in 27.3 days. Given that the mass of the Earth is 5.97 x 1024 kg, what is the avera
Roller Coaster G-Forces Roller coaster rides are infamous for forming accelerations and g-forces that are capable of transforming stomach contents within airborne projectiles.
a) Heat produced or absorbed at a junction is proportional to the current by the junction. b) This effect is produced when current is passed by junction of suitable materials.
Describe specific charge? Desfine Thomson's experiment to calculate e/m of an electron with relevant theory.
By what percentage should the pressure of a given mass of gas be increased,so as to decrease its volume by 10% at a constant temperature.
Chemical changes during: Discharging: The current will flow from positive to negative plate in the external circuit. As current now enters by negative plate, the negative
