### IPE Junior Inter Physics Model Question Paper - New Syllabus

IPE exams are approaching fast in Telangana and Andhra Pradesh.
Following is the Physics model paper for IPE exams of Junior Inter
students. The duration is 3 hours and maximum marks are 60. The model
question paper is given according to the new syllabus of Intermediate
Boards of AP and Telangana.

SECTION - A

I. (i) Very Short Answer Type questions.
(iii) Each question carries TWO Marks. 10 × 2 = 20
1. What is the contribution of S.Chandra Sekhar to Physics?
2. Distinguish between fundamental units and derived units.
3. Give an example, where, the velocity of an object is zero but its
acceleration is
not zero.
4. When two right angled vectors of magnitude 7 units and 24 units
combine, what is the magnitude of their resultant?
5. Can the coefficient of friction be greater than one?
6. A body freely falling from a certain height 'h' after striking a
smooth floor rebounds and rises to a height h/2. What is the
coefficient of resistution between the floor and the body?
7. 'Hydrogen is an abundance around the sun but not around the earth'. Explain.
8. A steel wire of length 20 cm is stretched to increase its length by
0.2 cm. Find the lateral strain in the wire, if the Poission's ratio
for steel is 0.19.
9. Can a substance contract on heating.
10. State Dalton's law of partial pressures.

SECTION - B

II. (i) Short Answer Type questions.
(iii) Each question carries FOUR Marks. 6 × 4 = 24

11. State parallelogram law of vectors. Derive an expression for the
magnitude and direction of the resultant vector.

remains constant.
20. Define simple harmonic motion. Show that motion of projection of a
particle performing uniform circular motion, on any diameter is simple
harmonic.
21. State Boyle's Law, Charle's Law. Hence, derive ideal gas equation.
Which of two laws is better for the purpose of thermometry and Why?
