Coherent light of wavelength lambda" = 500 nm" is sent through two narrow parallel slits in a large vertical wall. The two slits are 5 mu m apart. In front of the wall there is a semi cylindrical screen with its hori- zontal axis at the line running on the wall parallel to the slits and midway between them. Radius of the cylin- drical screen is "R = 2.0 m." Find the vertical height of the second order interference maxima from the centre (O) of the screen.

A spherical hollow cavity is made in a lead sphere of radius R such that is surface touches the outside surface of the lead sphere and passes through its centre. The mass of the sphere before hollowing was M with what gravitational force will the hollowed out lead sphere attract a small sphere of mass m which lies at a distacne d from the centre of the lead sphere on the straight line connecting the centeres of the spheres and that of the hollow if d =2R .

A thin copper rod of uniform cross section A square metres and of length L metres has a spherical metal sphere of radius r metre at tis one end symmetrically attached to the copper rod. The thermal conductivity of copper is K and the emissivity of the spherical surface of the sphere is epsi .The free end of the copper rod is maintained at the temperature T kelving by supplying thermal energy from a P watt source. Steady state conditions are allowed ot be established while the rod is properly insulated aginst heat loss from its lateral surface. Surroundings are at 0^@C Stefan's constant =sigmaW//m^(2) K^(4) . The net power that will be radiated out, P_S from the sphere after steady state condition are reached is

An atom is assumed to tbe spherical in shape and thus, the size of atom is generally given in terms of radius of the sphere and is called atomic radius. It is usually defined as the distance between the centre of the nucleus and outermost shell where electron are present. The exact measure of atomic radius is not easy due to following reasons: (i) The atom does not have well defined boundary. the probability of finding the electron is never zero even at large distance from the nucleus. (ii) It is not possible to get an isolated atom. the electron density around an atom is affected by the presence of neighbouring atoms, i.e., the size of the atom changes in going from one set of environement to another. (iii) the size of an atom is very small, of the order of about 1.2 Å,i.e., 1.2xx10^(-10)m . An estimate of the size of the atom can, however, be made by knowing the distance betweent he atoms in the combined state. the distance between the atoms, i.e., bond length are generally measured by the application of techniques such as X-ray differaction, electron diffraction, infrared spectroscopy, nuclear magnetic resonance spectroscopy, etc. However, bond lengths change with different type of bonding. Three types of radius are commonly used, i.e., (a) Covalent radius " " (b) crystals radius " " (c) Vander waal's radius Choose incorrect option regarding atomic radius
