Text Solution

AI Generated Solution

To solve the problem of finding the velocity and acceleration of a particle whose position at any instant is given by \( x \), we can follow these steps: ### Step 1: Understand the Definition of Velocity Velocity is defined as the rate of change of displacement with respect to time. Mathematically, it can be expressed as: \[ v = \frac{dx}{dt} \] where \( v \) is the velocity, \( x \) is the position of the particle, and \( t \) is time. ...

Assertion A particle is roting in a circle of radius 1 m. At some given instant, its speed is 2 ms^(-1) . Then acceleration of particle at the given instant is 4 ms^(-2) . Reason Centripetal acceleration at this instant is 4 ms^(-2) towards centre of circle.

For a particle executing SHM, x = displacement from mean position, v = velocity and a = acceleration at any instant, then

  • Assertion : A particle may be momentarily at rest and yet have non-zero acceleration. Reason : The zero velocity of a particle at any instant does not necessarily imply zero acceleration at that instant.

    A
    If both assertion and reason are trure and reason is the correct explanation of assertion.
    B
    If both assertion and reason are true but reason is not the correct explanations of assertion.
    C
    If assertion is true but reason is false.
    D
    If both assertion and reason is false

    Mark the correct statements for a particle go ing on a straight line: (a) If the velocity and acceleration have opposite sign, the object is slowing down. (b) If the position and velocity have opposite sign, the particle is moving towards the origin. (c) If the velocity is zero at an instant, the acceleration should also be zero at that instant. (d) If the velocity is zero for a time interval, the acceleration is zero at any instant within the time interval.
