four charged particles are at the corners of a square

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,..

They are deflected by electric and magnetic fields. The deflection is less compared to that of b particles, because a particles are heavy. They affect a photographic plate and cause fluorescence on striking a fluorescent material. They ionise the gas through which th..

Summary - Electric charge is a basic property of all matter. Unlike charges attract, like charges repel. Conductor allow flow of electric charges through them while insulators don't. Electric charges have three basic properties (a) Additivity (b) Qu..

Calculation of Number of Particles per Unit Cell of a Cubic Crystal System. Keeping the following points in mind we can calculate the number of atoms in a unit cell. An atom at the corner is shared by eight unit cells. Hence an atom at the corner contributes 1/8 ..

Alpha rays consist of stream of positively charged particles carrying charge of +2 units and a mass of four units on the atomic weight scale (i.e., 4 amu). They consist of 2 protons and 2 neutrons. In other words, these particles are hel..

A closed circular water tank of outer diameter 4 m and height 2 m is to be painted. Find the total charges for painting if the rate of painting is $10 per sq.m. [Take π = 3.] => $623 or $603 or $437 or $480..

An open top box is made by cutting a square of side x inches from each corner of a 10 inch by 18 inch piece of a cardboard and by folding up the sides.Which of the following represents the volume V of the box as a function of x ? => V = 180 x or V = 4 x 3 - 4..

A plot of land as shown has to be levelled. If the rate of levelling is $28 per square meter, then find the total charges for levelling. [Take a = 10 m, b = 8 m, c = 4 m, and π = 3.14] => $2767.52 or $3109.52 or $2893.52 or $2741.52..

Which is an incorrect statement? => A triangle has four sides. or A triangle has three corners. or A square has four sides. or A triangle has three sides...

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..
