The proton will circulate clockwise in a plane perpendicular to the the north direction.
The proton will move from the east to the west clockwise.

Why velocity of current equal to velocity of light?
Because charge particles produces magnetic field which causes electromagnetic force that's why moving charges move with the velocity equal to the velocity of light.
The difference between speed and velocity?
Speed is a scalar quantity and thus a general term; if a car is traveling at 60 mph that is its speed; Velocity is a vector quantity that has speed and direction associated with it. If a car is traveling at 60 mph due east that is its velocity. The two terms are often used interchangeably.
Is a force of friction a vector or scaler quantity?
Either, or both. Motion can be described in either vector or scalar terms. Speed is a scalar quantity, having only a magnitude. Velocity is a vector quantity, having both magnitude and direction. Acceleration is a vector quantity.
In direct current charges carries have a drift velocity but in alternating current there is no net velocity of the charge carriers. Explain why?
In direct current the charge carries always flow in the same direction, while in alternating current they change direction repeatedly, meaning overall there is no net direction.
Is viscous force present in air?
yes, viscous force is present in air. it is proportional to the velocity and area of the body and acts in the opposite direction of velocity.
What is the value of constant horizontal velocity?
In projectile motion, since , there's no force in the horizontal direction which can change the horizontal motion therefore the horizotal velocity remains conserved Vx=Vox= Vocos theta by using above formula , constant horizontal initial or final velocity can be found. since Initial = final horizontal velocity.
How fast is an object moving at the instant it hits the top of its trajectory?
Assuming that there is no velocity in the horizontal direction, then the velocity at that instant is zero.
What is the relationship between the electric magnetic and wave velocity vectors?
The wave velocity vector is parallel to the cross product of the electric and magnetic vectors.If you crank a wood screw from the Electric-field direction to the Magnetic-field direction, the screw proceedsinto the wood in the direction of the wave's velocity vector.Here's another advanced and highly technical way to keep these directions straight ...Curl the fingers of your right hand in the direction FROM the electric vector TO the magnetic vector.Your right thumb (when extended) points in the direction of the waves velocity vector, and alsothe "Poynting Vector"; that's the direction in which the wave carries energy.
Is the velocity of a horizontal moving object constant?
Only if the direction is constant and the speed is constant.
Which of the velocity component of projectile changes and other remain constant why?
the horizontal component remain unchanged because there in no acceleration in horizontal direction
A charged particle moving with a constant velocity enters a magnetic field?
when a charged particle is moving with some velocity it produces some magnetic field. If we place that charged particle in presence of external magnetic field it gets affected by that external field.
Why velocity of current equal to velocity of light?
Because charge particles produces magnetic field which causes electromagnetic force that's why moving charges move with the velocity equal to the velocity of light.
Where A Particle Is Projected Along A Linear Plane. The Horizontal Component Of The Velocity Is Twice The Vertical Component What Is The Initial Magnitude Of The Velocity And The Angle At Which It Is?
The initial velocity is sqrt(5) times the vertical component, and its angle relative to the horizontal direction, is 0.46 radians (26.6 degrees).
Does horizontal velocity effect the rate of vertical velocity?
No, horizontal velocity and vertical velocity are independent and have no effect on each other.
What is the difference between vector and scalor quantity?
Vectors include information about their direction, and are incomplete without it. Examples are displacement, velocity, acceleration, momentum, magnetic field. (Velocity is speed with direction.) Scalars are complete without stating any direction. Examples are temperature, cost, mass, speed. (Speed is velocity without direction.)
What is a horizontal line on a speed time graph?
It indicates that the object in question is moving at a constant velocity in the radial direction. It gives no information about motion in the transverse direction.
What is V - t graph?
It is a velocity-time graph in which time is plotted along the horizontal axis and the velocity of an object in a selected direction is plotted along the vertical axis.
