Millikan oil drop experiment (R.A. Millikan)
A popular experiment designed to compute the electronic charge. Drops of oil were carried past a consistent electric field among charged plates. After charging the drop along x-rays, he adjusted the electric field among the plates so that the oil drop was balanced exactly against the force of gravity. After that the charge on the drop would be known. Millikan did this frequently and found that all the charges he calculated came in integer multiples only of a certain smallest value, that is the charge on the electron.
It is explained by Heisenberg's uncertainty principle, it is impossible to calculate simultaneously both the position and the momentum of the particle. Let x and p be the uncert
Wien's displacement law constant, b It is the constant of the Wien displacement law. It contains the value 2.897 756 x 10 -3 m K.
Regard as an electron and a proton at an instant in time to be at a separation of 5 cm from each other. Presume the pair to be totally isolated from its surroundings in the vacuum
Two wires on a piano are the same length and are pulled by the same tension. wire 1 vibrates at a frequency 1.5 times the frequency of wire 2. Calculate the ratio of their masses (
composition of two SHM at right angle to each other and having time period in the ratio of 1: 2
1 Ampere: 1 ampere current is supposed to be flowing in a conductor if one coulomb of charge flows across section of the wire in one second.
What is the condition for resonance? Condition for resonance: The condition of frequency of the oscillatory circuit is equal to frequency of the vibrating rod as: 1/(2 Π
