Answer:
<em>The magnetic field's direction is towards the north</em>
<em></em>
Explanation:
The force on a positive charge in a uniform magnetic field is represented by the right hand rule. To determine the direction of the force, place your right hand with your palm up, and your thumb at 90° to the other fingers. If the fingers represent the magnetic field, and the thumb the direction of the positive charge, then the palm will push up in the direction of the force. But a negative charge like an electron pushes in exactly the opposite direction. So if you follow this rule, you will find that the magnetic field points towards the north.

Answer: No
Explanation:they do not exist electric field lines are only imaginary
The centripetal acceleration of the car is related to its speed by the relationship
where ac is the centripetal acceleration, v is the car's speed and r is the radius of the circular orbit.
Looking at the formula, we can see that if we triple the speed (v'=3v), the centripetal acceleration becomes
so, the centripetal acceleration increases by a factor 9.
