A positive charge is directed to a region of space where an electric field exists perpendicular to a magnetic field, as indicated in the figure. The electric field is directed vertically downwards and the magnetic field is directed into the page, if the particle follows path A, then

a.The electric force is less than the magnetic

b.The magnetic force is equal to the electric

c.The electric force can be greater or less than the magnetic force, but the speed of the particle does not change.
