As you need IIT JEE entrance exam model question paper for more better preparation for exam, here I am giving:

Two identical uniform discs roll without slipping on two different surfaces AB and CD
(see figure) starting at A and C with linear speeds v1 and v2, respectively, and always
remain in contact with the surfaces. If they reach B and D with the same linear speed
v1 = 3 m/s, then v2 in m/s is (g = 10 m/s2)

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 a maximum
period of nT years, then the value of n is

A Young’s double slit interference arrangement with slits S1 and S2 is immersed in water
(refractive index = 4/3) as shown in the figure. The positions of maxima on the surface of
water are given by x2 = p2m22  d2, where  is the wavelength of light in air (refractive
index = 1), 2d is the separation between the slits and m is an integer. The value of p is

A conductor (show in the figure) carrying constant current I is kept in the x-y plane in a
uniform magnetic field B. If F is the magnitude of the total magnetic force acting on the
conductor, then the correct statement(s) is(are)

(A), (B), (C)
To find magnetic force on a current wire vector length of current wire is taken. So length
of wire = 2 L + R
and F I L B
correct options are (A), (B) and (C).
