ConceptForce on a Moving Charge in Uniform Magnetic and Electric Fields

#### Question

Write the expression, in a vector form, for the Lorentz magnetic force $\vec{F}$ due to a charge moving with velocity $\vec{V}$ in a magnetic field $\vec{B}$. What is the direction of the magnetic force?

#### Solution

The Lorentz magnetic force is given by the following relation:

vecF=q(vecVxxvecB)

Here, q is the magnitude of the moving charge.

The direction of the magnetic force is perpendicular to the plane containing the velocity vector (vecV)and the magnetic field vector  (vecB)

Is there an error in this question or solution?
