IIT-JEE 2008 Paper 1 Offline Physics - Atoms and Nuclei Question 7 English

Fusion of two nuclei with mass number lying in the range of 1 < A < 50 will release energy

Fusion of two nuclei with mass numbers lying in the range of 51 < A < 100 will release energy

Fission of a nucleus lying in the mass range of 100 < A < 200 will release energy when broken into two equal fragments

Fission of a nucleus lying in the mass range of 200 < A < 260 will release energy when broken into two equal fragments

A particle of mass m and charge q, moving with velocity v enters Region II normal to the boundary as shown in the figure. Region II has a uniform magnetic field B perpendicular to the plane of the paper. The length of the Region II is $$l$$. Choose the correct choice (s).

IIT-JEE 2008 Paper 1 Offline Physics - Magnetism Question 7 English

The particle enters Region III only if its velocity $$v > {{qlB} \over m}$$

The particle enters Region III only if its velocity $$v < {{qlB} \over m}$$

Path length of the particle in Region II is maximum when velocity $$v = {{qlB} \over m}$$

Time spent in Region II is same for any velocity v as long as the particle returns to Region I

MCQ (More than One Correct Answer)

-2

In a Young's double slit experiment, the separation between the two slits is d and the wavelength of the light is $$\lambda$$. The intensity of light falling on slit 1 is four times the intensity of light falling on slit 2. Choose the correct choice(s).

If $$d=\lambda$$, the screen will contain only one maximum

If $$\lambda < d < 2\lambda$$, at least one more maximum (besides the central maximum) will be observed on the screen

If the intensity of light falling on slit 1 is reduced so that it becomes equal to that of slit 2, the intensities of the observed dark and bright fringes will increase

If the intensity of light falling on slit 2 is increased so that it becomes equal to that of slit 1, the intensities of the observed dark and bright fringes will increase
