šŸ”“ PHYSICS _MJC–3 (THERMAL PHYSICS & THERMODYNAMICS)

CIA ASSIGNMENT — 

Q1.

In an isothermal thermodynamic process, heat is supplied continuously to the system. Analyze the relationship between work done and change in internal energy, and explain its physical significance.

Q2.

Why is the Carnot engine considered an ideal heat engine? If the temperature of the source is increased while keeping the sink temperature constant, analyze how the efficiency of the engine will be affected.

Q3.

Entropy is often described as a measure of disorder. Justify this statement and analyze the role of entropy change in a spontaneous process of an isolated system.

 

šŸ”“ PHYSICS_MJC–4 : ELECTRICITY AND MAGNETISM

CIA ASSIGNMENT — 

Q1.

Using Gauss’s law, analyze the electric field due to a uniformly charged infinite plane sheet. Discuss how the result differs from that of a point charge and explain the physical significance of the difference.

Q2.

A charged particle enters a uniform magnetic field with its velocity making an angle with the field direction. Derive the expression for its trajectory and explain under what condition the particle moves in a helical path.

Q3.

Explain how displacement current modifies Ampere’s circuital law. Analyze its role in maintaining the continuity of current in a charging capacitor.

 

MIC–3 : THERMAL PHYSICS AND THERMODYNAMICS

CIA ASSIGNMENT — 

Q1.

Derive the mathematical expression for the efficiency of a Carnot engine and analyze why no real heat engine can be more efficient than a Carnot engine operating between the same two temperatures.

Q2.

Using the first law of thermodynamics, analyze the thermodynamic behavior of a system undergoing an adiabatic process. Explain the physical significance of the result.

Q3.

Discuss the concept of entropy from a thermodynamic point of view. Explain how entropy change determines the direction of a spontaneous process.
