Lorentx force can be calculated by using the formula.

Options

A. `vec(F) = q(vec(E) + vec(v) xx vec(B))`
B. `vec(F) = q(vec(E) - vec(v) xx vec(B))`
C. `vec(F) = q(vec(E) + vec(v) . vec(B))`
D. `vec(F) = q(vec(E) xx vec(v) + vec(B))`

Answer

A

Explanation

Lorentz force is given by
`vec(F)=vec(F)_(e)+vec(F)_(m)=qvec(E)+q(vec(v)xxvec(B))=q[vec(E)+(vec(v)xxvec(B))]`
