OSCILLATIONS QUIZ 12
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: During the oscillations of simple pendulum, the direction of its acceleration at the mean position is directed towards the point of suspension and at extreme position it is directed towards the mean position
Statement 2: The direction of acceleration of a simple pendulum at the mean position or at the extreme position is decided by the tangential and radial components of force by gravity
Solution
Q2.Statement 1: If the length of a spring is made n times, the spring factor of the spring becomes 1/n th of its original value.
Statement 2: Time of oscillation of a spring pendulum is T=2Ï€√(m/k)
Solution
Q3. Statement 1: The percentage change in time period is 1.5%, if the length of simple pendulum increases by 3%
Statement 2: Time period is directly proportional to length of pendulum
Solution
Q4. Statement 1: If the amplitude of a simple harmonic oscillator is doubled, its total energy becomes four times Statement 2: The total energy is directly proportional to the square of the amplitude of vibration of the harmonic oscillator
Solution
Q5.Statement 1: Acceleration is proportional to the displacement. This condition is not sufficient for motion in simple harmonic
Statement 2: In simple harmonic motion direction of displacement is also considered
Solution
Q6. Statement 1: The time period of a simple pendulum is of infinite length is infinite
Statement 2: The time period of simple pendulum is directly proportional to the square root of length.
Solution
Q7. Statement 1: Water in a U-tube executes SHM, the time period of mercury filled up to the same height in the U-tube be greater than that in case of water
Statement 2: The amplitude of an oscillating pendulum goes on increasing
Solution
Q8.Statement 1: Damped oscillation indicates loss of energy
Statement 2: The energy loss is damped oscillation may be due to friction, air resistance etc.
Solution
Q9.Statement 1: Two cubical blocks of same material and of sides a and 2a, respectively are attached rigidly and symmetrically to each other as shown. The system of two blocks is floating in water in such a way that upper surface of bigger block is just submerged in the water. If the system of blocks is displaced slightly in vertical directions, then the amplitude of oscillation on either side of equilibrium position would be different
Statement 2: The force constant on two sides of equilibrium position in the above-described situation is different
Solution
Q10. Statement 1: The total energy of a particle performing simple harmonic motion could be negative
Statement 2: Potential energy of a system could be magnetic
Solution
