  • a)
    The angular momentum of the charge – q is constant
  • b)
    The linear momentum of the charge – q is constant
  • c)
    The angular velocity of the charge –q is constant
  • d)
    The linear speed of the charge –q is constant
Correct answer is option 'A'. Can you explain this answer?

Under the influence of the Coulomb field of charge + Q, a charge &ndas...
The situation is shown in the figure which is similar to a planet revolving around sun. The distance of – q from + Q is changing, therefore, force between the charges will change.   
The speed of the charge – q will be greater when the charge is nearer to + Q as compared to when it is far.
Therefore,  the angular velocity of charge – q is also variable. The direction of the velocity changes continously, therefore, linear momentum is also variable.
The angular momentum of (– q) about Q is constant because the torque about + Q is zero.
