(2,3,-1) and (-2,-4,3)-DIS IS POSITION VECTOR.
FIND LINE PASSING THRU DIS.
IT IS -4i +-7j+4k
 NW PROJECTION WILL BE
  {
(4i-3j+k).(-4i -7j+4k)}/81=
=(-16+21+4)/9
=1

AREY SIMPLE PUT THE FORMULA
  • The plane passing through three points \bold p_1 = (x_1,y_1,z_1) , \bold p_2 = (x_2,y_2,z_2) and \bold p_3 = (x_3,y_3,z_3) can be defined as the set of all points (x,y,z) that satisfy the following determinant equations:
\begin{vmatrix}  x - x_1 & y - y_1 & z - z_1 \\ x_2 - x_1 & y_2 - y_1& z_2 - z_1 \\ x_3 - x_1 & y_3 - y_1 & z_3 - z_1  \end{vmatrix} =\begin{vmatrix}  x - x_1 & y - y_1 & z - z_1 \\ x - x_2 & y - y_2 & z - z_2 \\ x - x_3 & y - y_3 & z - z_3  \end{vmatrix} = 0.

At the beginning of the twentieth century, experimental evidence suggested that atomic particles were also wave-like in nature. For example, electrons were found to give diffraction patterns when passed through a double slit in a similar way to light waves. Therefore, it was reasonable to assume that a wave equation could explain the behaviour of atomic particles.

Schrodinger was the first person to write down such a wave equation. Much discussion then centred on what the equation meant. The eigenvalues of the wave equation were shown to be equal to the energy levels of the quantum mechanical system, and the best test of the equation was when it was used to solve for the energy levels of the Hydrogen atom, and the energy levels were found to be in accord with Rydberg's Law.

It was initially much less obvious what the wavefunction of the equation was. After much debate, the wavefunction is now accepted to be a probability distribution. The Schrodinger equation is used to find the allowed energy levels of quantum mechanical systems (such as atoms, or transistors). The associated wavefunction gives the probability of finding the particle at a certain position.

Schrodinger Equation

The Schrodinger equation plays the role of Newton's laws and conservation of energy in classical mechanics - i.e., it predicts the future behavior of a dynamic system. It is a wave equation in terms of the wavefunction which predicts analytically and precisely the probability of events or outcome. The detailed outcome is not strictly determined, but given a large number of events, the Schrodinger equation will predict the distribution of results.

The kinetic and potential energies are transformed into the Hamiltonian which acts upon the wavefunction to generate the evolution of the wavefunction in time and space. The Schrodinger equation gives the quantized energies of the system and gives the form of the wavefunction so that other properties may be calculated.

i also think ans is c
u can make intervals like
0<=3x2+1<1
nd 1<=3x2+1<2
nd 2<=3x2+1<3
nd 3<=3x2+1<4
then u will get values of x
upto wich it gives 0,1,2,3

yup
in gauss lass electric field will be due to all charges present in surroundings
whether outside or inside gaussian surface.
bt flux will only due to charges present inside gaussian surface.
