"The exact path of electron in 2p-orbital cannot be determined." The above statement is based upon:

The energy of an electron of 2p_(x) orbital is :

'The solubility of a gas is directly proportional to the pressure of the gas''. The above statement is based upon.

A star like the sun has several bodies moving around it at different distances. Consider that all of them are moving in circular orbits. Let r be the distance of the body frm the centre of the star and let its linear velocity be v, angular velocity omega , kinetic energy K, gravitational potential energy U, total energy E and angular momentum p. As the radius r of the orbit increases, determine which of the above quantities increase and which one decrease.

In a chamber, a uniform magnetic field of 6.5 G (1 G = 10^-4 T) is maintained. An electron is shot into the field with a speed of 4.8 xx 10^6 m s^-1 normal to the field. Explain why the path of the electron is a circle. Determine the radius of the circular orbit. (e = 1.5 xx 10^-19 C. m_e= 9.1x10^-31 kg)

An electron gun with its collector at a potential of 100 V fires out electrons in a spherical bulb containing hydrogen gas at low pressure (~10^-2 mm of Hg) . A magnetic field of 2.83 xx 10^-4 T curves the path of the electrons in a circular orbit of radius 12 cm. detremine e/m from the data.

Determine the speed of the electron in the n=3 orbit of hydrogen atom.

The mean free path of conduction electrons in copper is about 4 xx 10^(-8) m . Find the electric field which can give 2 eV energy (on the average) to a conduction electron in a copper block.

The orbital angular momentum of 3p electron is :

Statement :1. 2-Pentanol and 3-pentanol cannot be distinguished by iodoform test. Statement: 2.2-Pentanol and 3-pentanol both are secondary alcohols.

The radius of the first electron orbit of a hydrogen atom is 0.5overset(@)A . The electron moves in this orbit with a uniform speed of 2.2xx10^(6)m.s^(-1). What is the magnetic field produced at the centre of the nucleus due to the motion of this electron?
