You are looking for the Delhi Combined Entrance Exam (Delhi CEE) Physics & Chemistry question paper, I am giving here:

Physics:

The law of far a day is obtained by conservation of :
(1) Charge (2) Energy (3) Energy and magnetic field (4) Magnetic field

Two thin lenses are put close to each other, focal length of the combination is :
(1) less than the small focal length
(2) more than the bigger focal length
(3) equal to the arithmetical average of the focal length
(4) equal to the geometrical average of the focal length

5. A car is moving on a horizontal circular path with 10 m/s constant speed. A rigid
body is suspended from ceiling of car with a 1 m. long light rod, the angle between
rod and path is :
(1) 600 (2) 450 (3) 300 (4) zero

11. In which of the waves the energy is not propagated :
(1) em waves
(2) longitudional waves
(3) stationary waves
(4) transverse waves

If the intensity and frequency of incident light is doubled then :
(1) photo electric current will become is times
(2) kinetic energy of the emitted electron will be increased and current will be 2 times
(3) kinetic energy of electrons will be 4 times
(4) the kinetic energy of electrons will be 2 times

Chemistry:

Which one of the following is the correct statement?
i. Chlorides of both beryllium and aluminium have bridged chloride structures in solid phase.
ii. B2H6.2NH3 is known as 'inorganic benzene'.
iii. Boric acid is a protonic acid.
iv. Beryllium exhibits coordination number of six.

The pKa of a weak acid, HA is 4.80. The pKb of a weak base, BOH, is 4.78. The pH of an aqueous solution of
the corresponding salt, BA, will be
i. 7.01
ii. 9.22
iii. 9.58
iv. 4.79

Amount of oxalic acid present in a solution can be determined by its titration with KMnO4solution in the
presence of H2SO4. The titration gives unsatisfactory result when carried out in the presence of HCl, because HCl
i. reduces permanganate to Mn2+.
ii. oxidises oxalic acid to carbon dioxide and water.
iii. gets oxidised by oxalic acid to chlorine.
iv. furnishes H+ ions in addition to those from oxalic acid.

Which of the following factors is of no significance for roasting sulphide ores to the oxides and not subjecting the sulphide ores to carbon reduction directly?
i. Metal sulphides are less stable than the corresponding oxides.
ii. CO2is more volatile than CS2.
iii. Metal sulphides are thermodynamically more stable than CS2.
iv. CO2is thermodynamically more stable than CS2.
