Hello dear as you need the jee advanced previous year question papers on your request I am providing you the paper……..

1.Consider a hydrogen atom with its electron in the nth orbital. An electromagnetic radiation of wavelength 90 nm is used to ionize the atom. If the kinetic energy of the ejected electron is 10.4 eV, then the value of n is (hc = 1242 eV nm)

2. A bullet is fired vertically upwards with velocity v from the surface of a spherical planet. When it reaches its maximum height, its acceleration due to the planet's gravity is 1/4th of its value at the surface of the planet. If the escape velocity from the planet is v v N e c s = , then the value of N is (ignore energy loss due to atmosphere)

3.A nuclear power plant supplying electrical power to a village uses a radioactive material of half life T years as the fuel. The amount of fuel at the beginning is such that the total power requirement of the village is 12.5% of the electrical power available from the plant at that time. If the plant is able to meet the total power needs of the village for maximum period of nT years, then the value of n is

4. Consider a Vernier callipers in which each 1 cm on the main scale is
divided into 8 equal divisions and a screw gauge with 100 divisions on its
circular scale. In the Vernier callipers, 5 divisions of the Vernier scale
coincide with 4 divisions on the main scale and in the screw gauge, one
complete rotation of the circular scale moves it by two divisions on the linear
scale. Then:

(A)If the pitch of the screw gauge is twice the least count of the Vernier
callipers, the least count of the screw gauge is 0.01 mm.

(B)If the pitch of the screw gauge is twice the least count of the Vernier
callipers, the least count of the screw gauge is 0.005 mm.

(C)If the least count of the linear scale of the screw gauge is twice the least
count of the Vernier callipers, the least count of the screw gauge is 0.01 mm.

(D)If the least count of the linear scale of the screw gauge is twice the least
count of the Vernier callipers, the least count of the screw gauge is 0.005
mm

5. Planck's constant h, speed of light c and gravitational constant G are used to form a unit of length L and a unit of mass M. Then the correct option(s) is (are)
(A)M c µ
(B)M G µ
(C)L h µ
(D)L G
