Which force field can accelerate an electron but never change its speed?

I would say a magnetic field. When an electron enters a magnetic field that is oriented perpendicular to its path of travel it causes the electron to loop in a circle. While the speed stays the same the velocity is constantly changing due to the circular motion. Hence same speed but undergoing an acceleration.

Why do electrons in a uniform magnetic field travel in a circular path?
It's because of how magnetic force is. The magnetic force is always perpendicular to both the magnetic field and the velocity of the electron, or any charged particle. If you draw x's on a piece of paper, representing the direction of the magnetic field into the paper, then draw a short vertical line up, representing the electron velocity, the magnetic force will be horizotal to the right. This causes the velocity to change direction a little toward the right. But now the force must change direction a little, etc., etc, until you get a circular path. BTW, you only get a circular path if the initial velocity is in the plane of the paper, perpendicular to the field. If the electron comes in at an angle from outside the paper the path will be a "screw" shape, circular and forward at the same time.
What must be applied to an object to change its motion or direction?
If an object is at rest, a force must be applied to accelerate it (start it moving).
An unbalanced force can cause an object to change its speed and or?
The object will speed up, slow down or change direction. An unbalanced force (net force) acting on an object changes its speed and/or direction of motion. ... If however, the forces are balanced (in equilibrium) and there is no net force, the object will not accelerate and the velocity will remain constant.
What will an object always do when acted on by an unbalanced force?
There's no such thing as "an unbalanced force". But when the entire group of forceson an object is unbalanced, then the object must accelerate.
Which type of force can change the total momentum of a closed system?
Any external force applied on the system. Type of force ? ; from collision with another system, from a gravity field, gravity force. Depending on the system, from other field forces like electromagnetic force.
What will be the effect on the motion of electron if it travels along the dirction of electric field?
The "direction" of the electric field is defined as the direction of the force it exerts on a small positive charge. The direction of the force on an electron in the field is exactly opposite to the direction of the field, and its effect is to accelerate the electron in the direction of the force.
What effects does gravity have on planets?
The same effect as it has on any other object. The gravitational field produces a force; this force, acting on a planet, will accelerate it - that is, it will change its velocity.
A net force causes an object to?
Accelerate, motion is generated by applying force to mass.
Force experienced by an electric field E is F N What will be the force on a proton in the same field. Take mass of the proton to be 1836 times mass of an electron?
Force experienced will be same in magnitude as that of electron but in opp direction i.e. F=qE.
What force makes object change positions?
Any force will accelerate an object to change its position. It might be gravitational, electric, magnetic, etc -- even muscle force, which is ultimately electrical at the atomic level. There are many kinds of forces, all of which can accelerate objects that have mass.
What is an force that can cause an object to change its speed and direction.?
A basic physics answer for this is that a net force (or unbalanced force) will cause an object to accelerate, that is, cause the object to change its speed and/or direction.
The force on an electron moving in a magnetic field will be the largest when its direction is?
perpendicular to the magnetic field direction
How does Newtons first law relate to the equilibrium rule?
If the forces are balanced (in other words, the net force on an object is zero), then the object will not accelerate (its velocity will not change).If the forces are balanced (in other words, the net force on an object is zero), then the object will not accelerate (its velocity will not change).If the forces are balanced (in other words, the net force on an object is zero), then the object will not accelerate (its velocity will not change).If the forces are balanced (in other words, the net force on an object is zero), then the object will not accelerate (its velocity will not change).
An object will accelerate in the direction of what force?
An object will accelerate in the direction of net force
If a stationary electron sat inside a stationary magnetic field would the magnetic field cause the electron to move?
Stationary charge don't produce a magnetic field. because it has no velocity in it, without flow of electron we can't find electricity and for that we have no magnetic field for a stationary charge. It produce only electric field.
A net force greater than zero will cause an object to?
... to accelerate.... to accelerate.... to accelerate.... to accelerate.
When does the object of the forces does not move?
If no force is applied to an object, the object will not accelerate - its velocity won't change.
