At. a certain instant, a proton is moving in the positive x direction through a magnetic field in the negative z direction. What is the direction of the magnetic force exerted on the proton? (a) positive z direction (b) negative z direction (c) positive y direction (d) negative y direction (e) The force is zero.

Sagot :

The direction of the magnetic force exerted on the proton is positive y-direction.

Here proton(positively charged) moves in the positive x direction in a region where there is a magnetic field in the negative z direction. To find the direction of the magnetic force exerted on the proton, the magnetic force is given by:

[tex]F_{B} = B[/tex]×[tex]q[/tex]×vsinθ

The vector v x B points along the positive y-direction. (Right-hand thumb rule). For a proton, q is positive, so the Force vector F = q v x B also points along the positive y-direction. With a force on it in the positive y-direction, the proton will move in a circle in a plane parallel to the XY-plane.

[tex]F_{B} = qV[/tex]×[tex]B[/tex]

[tex]F_{B}[/tex]      = i ×(-k) = +j

Hence magnetic force acts in the positive y-direction.
