Q1
Two heavy spheres each of mass 100 kg and radius 0.10 m are placed 1.0 m apart on a horizontal table. What is the gravitational force and potential at the mid point of the line joining the centres of the spheres ? Is an object placed at that point in equilibrium? If so, is the equilibrium stable or unstable ?
Q2
As you have learnt in the text, a geostationary satellite orbits the earth at a height of nearly 36,000 km from the surface of the earth. What is the potential due to earth's gravity at the site of this satellite ? (Take the potential energy at infinity to be zero). Mass of the earth = , radius = 6400 km.
Q3
A star 2.5 times the mass of the sun and collapsed to a size of 12 km rotates with a speed of 1.2 rev. per second. (Extremely compact stars of this kind are known as neutron stars. Certain stellar objects called pulsars belong to this category). Will an object placed on its equator remain stuck to its surface due to gravity ? (mass of the sun = ).

An ideal gas initially at 350 K is heated at a constant volume of 2.0 moles from a pressure of 35 Pa to a pressure of 58 Pa. In the process, 69 J of heat is gained by the gas. Find the change in internal energy of the gas. 2. Corrected_text: A metal rod is in thermal contact with a constant temperature reservoir at 145°C at one end and another reservoir at 32°C at the other end. Compute the total change in entropy of the system that occurs when 3250 J of heat is conducted through the bar, from one end to the other. 3. Corrected_text: If you hold a concave spherical mirror of radius of curvature 30 cm in front of your face so that the image you see of yourself is inverted and only one-half actual size, how far is the mirror from your face? 4. Corrected_text: Light of wavelength 650 nm is incident perpendicularly on a thin film (n = 1.33) suspended in air. Find the smallest two thicknesses for which the reflections undergo fully constructive interference. 5. Corrected_text: In a Young's double slit arrangement, the two slits are separated by a distance equal to 45 times the wavelength of the light used. a) What is the angular location of the first side maximum? b) What is the distance between this maximum and the central maximum on a screen that is located 62.0 cm from the slits? 6. Corrected_text: An ideal engine whose low temperature reservoir is at 18°C has an efficiency of 35%.

Use Simulink-MATLAB to simulate Example 3.1. Students will use Simscape -> Power Systems -> Specialized Technology to simulate their model. Students will also report their simulations and results and submit them through Canvas. Additionally, students will attach their simulation files along with their assignment reports. Example 3.1: A half-bridge single-phase inverter with a load connected to the center tap point of the capacitors is designed to provide 60 Hz at its AC output terminal and is supplied from a PV source with 380 VDC. Assume the switching frequency is 420 Hz (Mf is 7) and amplitude modulation Ma is 0.9. Write a MATLAB m-file code to display the waveforms of the inverter. Include the sine wave, triangular wave, and the output wave Vao.
