PHYSICS Paper III Phy- 103 PRACTICALS Max. Marks : 40 Time : 3 Hrs. SPECIAL NOTES 1. Do any eight experiments . 2. The students are required to calculate the error involved in a particular experiment (percentage error). NOTE 1. Distribution of Marks : Experiment : = 20 marks Viva Voce : = 10 marks Lab Record : = 10 marks Total = 40 marks For giving marks under Lab. Record each college will maintain practical assessment record by using the following procedure :- 1. Each student has to peform a minimum number of experiments prescribed in the syllabus. 2. After the completion of a practical the teacher concerned will check the note- book and conduct the viva-voce of each student to find out how much concepts related to the theoertical and experimental part of the experiment he/she has understood. According to his/her performance marks will be recorded in their practical note book. These marks will constitue the lab record. 3. To complete the final marks for lab. record a separate register for each class of B.Sc will be maintained. The Student will be assigned a separate page on the register. On this page the marks obtained by the student in different practicals will be recorded. While taking the final average the total marks obtained willbe divided by the total no. of required practicals, instead of the number of practicals performed by the student. This record will be signed by the concerned teacher. 4. The lab. record register will be presented to the external practical examiners for lab. record marks. The external examiners will verify the record randomly. B.Sc. PHYSICS Paper III- PHY 103 PRACTICALS Max. Marks : 40 Time : 3 Hours 1. Moment of Inertia of a fly-wheel 2.
