four charged particles are held fixed

The e/m ratio of the anode rays obtained from hydrogen gas was found to be highest and equivalent to 9.58 x 10 4 C g - 1 . These particles carried a charge of 1.602 x 10 - 1 9 C. Thus, the mass of the positive particle from hydrogen gas is,..

Although Rutherford's model was enormously successful at explaining the scattering of alpha particles, there was a problem when the experimental data were used to calculate the mass of the nucleus. From the results of the scattering experiments, it was possible to calculate the char..

A carpenter charges a fixed fee of $40 for coming to job plus $8 for each hour he works. If he works for x hours, which of the graphs represents the money(y) he gets? => Graph 2 or Graph 1 or Graph 3 or Graph 4..

A particle is moving along a straight line so that at time t , its displacement S from a fixed point in the line is given by S = 4 α sin(7 β t + γ) where α , β , γ are constants. If V and f are the velocity and acceleration of the ..

Question: When sound travels through air, the air particles ______. 1. vibrate along the direction of wave propagation 2. vibrate but not in any fixed direction 3. vibrate perpendicular to the direction of wave propagation 4. do not vibrate ..

The Solid State - Solids are substances having definite volume and definite shape. In terms of kinetic molecular model, in solids there is a regular order in the arrangement of the constituting particles (atoms, molecules or ions) i.e. the particles constituting the solids occup..

Formation of Molecule Atoms of most of the elements do not exist independently. They either form molecules or ions. An atom having a charge on it is called an ion. When an atom loses or gains charge, it gets converted into a positively or negatively charged ion res..

Ernest Rutherford, an energetic New Zealander working in England, was studying the properties of particles spontaneously emitted by radioactive substances. Of particular interest was a positively charged, relatively heavy emission named alpha particle. Quantities of s..

In ionic solids, the constituent particles are ions. Coulombic forces of attraction hold oppositely charged ions together, to form ionic bonds. Each ion is surrounded by a certain fixed number of the ions of the opposite charge (as its nearest neighbour..

Solids are closely packed condensed states, with their constituent particles (atoms, ions or molecules) held together by strong physical or chemical bonds. These particles show a definite regular arrangement in a long range order. Solids may be broadly categorised into..
