Options

  1. AAn undeformed spring of spring constant k is connected to a bead of mass m which can move along a frictionless rod as
  2. BAn undeformed spring of spring constant k is connected to a bead of mass m which can move along a frictionless rod as
  3. CAn undeformed spring of spring constant k is connected to a bead of mass m which can move along a frictionless rod as
  4. DAn undeformed spring of spring constant k is connected to a bead of mass m which can move along a frictionless rod as

Correct answer

A. An undeformed spring of spring constant k is connected to a bead of mass m which can move along a frictionless rod as

Step-by-step solution

If magnetic field is perpendicular and into the plane of the paper, it is represented by cross ⊗\otimes and if the direction of the magnetic field is perpendicular out of the plane of the paper it is represented by dot ⊙\odot.
