2023 2024 MBA - IIT Exam Model Papers

The previous year Indian Institutes of Technology-Joint Entrance Examination (IIT-JEE) (Mains) question paper is as follows:

A time dependent force F=6t acts on a particle of mass 1 kg. If the particle starts from rest, the work done by the force during the first 1 sec. will be :
(1) 4.5 J
(2) 22 J
(3) 9 J
(4) 18 J

A capacitance of 2 F is required in an electrical circuit across a potential difference of 1.0 kV. A large number of 1 F capacitors are available which can withstand a potential difference of not more than 300 V. The minimum number of capacitors required to achieve this is :
(1) 2
(2) 16
(3) 24
(4) 32

A diverging lens with magnitude of focal length 25 cm is placed at a distance of 15 cm from a converging lens of magnitude of focal length 20 cm. A beam of parallel light falls on the diverging lens. The final image formed is:
(1) real and at a distance of 40 cm from convergent lens.
(2) virtual and at a distance of 40 cm from convergent lens.
(3) real and at a distance of 40 cm from the divergent lens.
(4) real and at a distance of 6 cm from the convergent lens.

In a Youngs double slit experiment, slits are separated by 0.5 mm, and the screen is placed 150 cm away. A beam of light consisting of two wavelengths, 650 nm and 520 nm, is used to obtain interference fringes on the screen. The least distance from the common central maximum to the point where the bright fringes due to both the wavelengths coincide is :
(1) 1.56 mm
(2) 7.8 mm
(3) 9.75 mm
(4) 15.6 mm
