Electrons moving with different speeds enter a uniform magnetic field in a direction perpendicular field. They will move along circular paths, time periods of rotation will be :

In SHM , the phase constant can be shown as?

Equation of motion of a particle is given by , where is the acceleration, is the displacement from the mean position and any constant. The time period of the particle is

If SHM is represented by , then is

If is the magnitude of velocity is the magnitude of displacement, then at the mean position of the particle performing SHM-

If simple harmonic motion is represented by , then is-

One end of a rod of length is fixed to a point on the circumference of a wheel of radius . The other end is sliding freely along a straight channel passing through the centre of the wheel as shown in the figure below. The wheel is rotating with a constant angular velocity about . Taking , the motion of the rod is

Match the following entries in column-I and column-II with respect to an oscillating spring-block system:
column-I | column-II | ||
(a) | Mass of the block is doubled | (i) | Energy of oscillation becomes times |
(b) | Spring constant is made times | (ii) | Speed of block becomes times |
(c) | Amplitude of oscillations is doubled | (iii) | becomes times |
(d) | Angular frequency is doubled | (iv) | Time period becomes times |

A body is performing simple harmonic motion of amplitude and time period . The figure shows position-time graph of the body. At any time , acceleration of the body is , then which of the following graphs is/are appropriate?

A block attached to a spring vibrates with a frequency of on a frictionless horizontal table. Two springs identical to the original spring are attached in parallel to ablock placed on the same table. So, the frequency of vibration of the block is

The type of graph between length of a simple pendulum and time period is -


Displacement vs time curve for a particle performing SHM is as shown in the figure.
Which of the following statement is correct?

If the frequency of human heart is , the number of times the heart beats in is

A body of mass and charge is connected to a spring of spring constant . It is oscillating along -direction about its equilibrium position in horizontal plane, taken to be at , with an amplitude . An electric field is applied along the -direction. Which of the following statements is correct?

The potential energy of a particle of mass moving along the -axis, is given by where is in metres. Choose the wrong option.

A spring has a natural length of and a force constant of . A body of mass is suspended from it and the spring is stretched. If the body is pulled down to a length of and released, it executes simple harmonic motion. What is the net force on the body when it is at its lowermost position of its oscillation? (Take ).

A particle is fastened at the end of a string and is whirled in a vertical circle with the other end of the string being fixed. The motion of the particle is,

The restoring force of SHM is maximum when particle

Assertion: The time period of the SHM of a system consisting of a mass attached to spring does not depend on whether it is hanging vertically from fixed support or lying on a horizontal table with another end of the spring fixed.
Reason: In the spring block system gravity affects only the mean position. The time period depends only on mass & spring constant.
