12th-cet

A particle starts oscillating simple harmonically from its equilibrium position. Then the ratio of kinetic and potential energy of the particle at time T / 12 is ( T – time period)

12th-cet

The time taken by a particle executing simple harmonic motion of period ‘T’ to move from the mean position to half the maximum displacement is

12th-cet

The bob of a simple pendulum of ‘length ‘l’ is pulled through an angle ‘θ’ from its equilibrium position and them released. When it passes through its equilibrium position, its speed is given by: (g = acceleration due to gravity)

12th-cet

A body of mass ‘M’ executes SHM Along x-axis with frequency ‘n’. At a distance x from the mean position, the body has kinetic energy ‘K’ and potential energy ‘P’. The amplitude of oscillation of the SHM is

12th-cet

The kinetic energy of a particle executing a linear SHM is 16 J, when it is in the mean position. If the amplitude is 25 cm, periodic time of the particle in second is (Mass of the particle = 51.2 g)

12th-cet

The length of the seconds pendulum is 1 m on earth. If the mass and diameter of any planet is 1.5 times that of the earth, the length of the seconds pendulum on that planet will be nearly

12th-cet

Two simple harmonic motions of angular frequency 100 rad/sec and 1000 rad/s have the same displacement amplitude. The ratio of their maximum acceleration is

12th-cet

If a body is executing simple harmonic motion then

12th-cet

A body executing simple harmonic motion has a maximum acceleration equal to 24 ms¯² and maximum velocity of 16 ms-¹, the amplitude of the simple harmonic motion is

12th-cet

The mass M shown in the figure oscillates in simple harmonic motion with amplitude A. The amplitude of the point P is
