For a positive charged particle (q) moving with a velocity (v) in a magnetic Filed of flux density B, the force (F) acting on the charge particle is given by the expression?

q = Fv × B
F = v × B/q
q = v × B/F
F = qv × B

Answer: F = qv × B

Explanation

The force $F$ acting on a charged particle moving in a magnetic field is given by the Lorentz force equation, which can be expressed as:

$F = q(mathbf{v} times mathbf{B})$

Where:

$F is the force acting on the particle,$
$q$ is the charge of the particle,
$mathbf{v}$ is the velocity vector of the particle,
$B$ is the magnetic flux density (magnetic field strength) vector.

The cross product $v \times B$ indicates that the direction of the force is perpendicular to both the velocity and the magnetic field vectors. Thus, the correct expression for the force is $F = q v \times B$ .
