A charge is passing through a static magnetic field. The velocity of the charge makes a 90o angle with the field. The force exerted by the magnetic field does work on the charge. Group of answer choicesTrueFlase

Respuesta :

Answer:

True

Explanation:

F = qvBsin90

At 90 degree magnetic lines are been cut through and the charge produces a force in newton.

Answer:

True

Explanation:

Magnetic Force:

The magnetic force exerted on a moving charge with a velocity in the presence of a magnetic field is given by

F = qvBsinθ

  • Where θ is the angle between velocity and magnetic field B.
  • When B and v are parallel then sinθ is 0 and therefore, magnetic force is zero.
  • When B and v are perpendicular then sinθ is 1 therefore, magnetic force is maximum.
  • The direction of magnetic force can be found using right hand rule.
  • Please note that there is no magnetic force exerted on static charges, magnetic force is exerted when charges are moving.
