positively charged particle trajectories
(always, never, the same as)
follow electric field lines, because
(electric field lines are defined by the path positive test charges travel.,
the particle velocities may or may not be in the same direction as the electric field lines.,
positive charges repel each other and, therefore, are repelled by electric field lines.,
the electric force on a positively charged particle is in the same direction as the electric field.)

Positively charged particle trajectories always follow electric field lines because the electric force on a positively charged particle is in the same direction as the electric field.

Explanation:

For any positive charge the electric field emerges radially outwards and it goes radially inwards for the negative charges.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
