OSCILLATIONS QUIZ 15
Dear Readers,
JEE Advanced Physics Syllabus can be referred by the IIT aspirants to get a detailed list of all topics that are important in cracking the entrance examination. JEE Advanced syllabus for Physics has been designed in such a way that it offers very practical and application-based learning to further make it easier for students to understand every concept or topic by correlating it with day-to-day experiences. In comparison to the other two subjects, the syllabus of JEE Advanced for physics is developed in such a way so as to test the deep understanding and application of concepts..
Q1. Statement 1: The bob of simple pendulum is a ball full of water. If a fine hole is made at the bottom of the ball. Then the time period will no more remain constant.
Statement 2: The time period of a simple pendulum does not depend upon mass.
Solution
Q2.Statement 1: Soldiers are asked to break steps while crossing the bridge
Statement 2: The frequency of marching may be equal to the natural frequency of bridge and may lead to resonance which can break the bridge
Solution
Q3. Statement 1: If stretched by the same amount, work done on S1, will be more than that on S2
Statement 2: k1 is less than k2
Solution
Q4. Statement 1: When a girl sitting on a swing stands up, the periodic time of the swing decreases. Statement 2: When the girl stands up more weight is felt on the string of swing.
Solution
Q5.Statement 1: When a simple pendulum is made to oscillate on the surface of moon, its time period increases
Statement 2: Moon is much smaller as compared to earth
Solution
Q6. Statement 1: A spring of force constant k is cut into two pieces whose lengths are in the ratio 1:2. The force constant of series combination of the two parts is √3k/2
Statement 2: The spring connected in series are represented by k=k1+k2.
Solution
