Ques 1: A particle has initial velocity = 10 m/s and has an acceleration of 2 m/s². After how much time will it have velocity equals to 60 m/s ?

Ans. 25 sec
Sol. v = u + at
60 = 10 + 2t
t = 25 sec.

2. An atom follows Bohr’s model. If the radius of e^– in first orbit is ‘a’. what is the de Broglie wave
length of electron present in third orbit.

4. A particle moving in uniform circulation motion goes from A to B separated by an angle of 120°
w.r.t. center of the circle. Find the magnitude of average velocity of particle from A to B.

7. Electric energy density and magnetic energy density of an electromagnetic wave is given by :

10. Which of the following statement is incorrect according to Kepler’s law for a planet :
(1) Total energy of planet is constant              (2) linear speed is constant
(3) areal velocity is constant                            (4) All of the above

Ans. (2)

15. Assertion : The phase difference of two light waves change if they travel through different media
having same thickness but different indices of refraction.
Reason : The wavelength of waves are different in different media.
Ans. Both are correct and R is the correct explanation of A.

18. Assertion (A) : In forward biased p-n junction, diffusion current is from p-region to n-region.

Reason (R) : Diffusion takes place due to concentration gradient.
Ans. Both are correct and R is the correct explanation of A.

20. Two different photosensitive materials having work function 4.1 eV and 5.1 eV respectively, are
illuminated with light of sufficient energy to emit electron. If the graph of stopping potential vs.
frequency is drawn for these two different photosensitive materials, the ratio of slope of graph
for these two materials is:
Ans. 1 : 1

22. Assertion : When toothpaste is pressed, it follows Pascal’s law.
Reason : When pressure is applied on a fluid it is distributed uniformly throughout the fluid in all
direction and on the wall of the container.
Ans. Both are correct and R is the correct explanation of A.
