Answer:
The change in potential energy is 
Explanation:
From the question we are told that
The magnitude of the uniform electric field is 
The distance traveled by the electron is 
Generally the force on this electron is mathematically represented as
Where F is the force and q is the charge on the electron which is a constant value of 
Thus
Generally the work energy theorem can be mathematically represented as
Where W is the workdone on the electron by the Electric field and 
is the change in kinetic energy
Also workdone on the electron can also be represented as
Where 
considering that the movement of the electron is along the x-axis
So
substituting values
Now From the law of energy conservation
Where 
is the change in potential energy
Thus
They would have disliked that they had to relearn how to measure.

Answer:
A. The same amount
Explanation:
The acceleration at which objects free falls to the ground on Earth is constant and its value is always 
, regardless of their mass (in this problem we neglect air resistance).
So, it doesn't matter if the two rocks are different or they are launched from different heights: their acceleration will be exactly the same.
This can be proved this way: first of all, the force of gravity exerted on every object is equal to the weight of the object,
where m is the mass of the object and g the acceleration of gravity.
However, we also know for Newton's second law that
where a is the acceleration of the object.
Combining the two equations,
So, the acceleration of an object in free fall is exactly the acceleration of gravity.
The answer is, "an unbalance force has acted on the vehicle". The vehicle will not change its states, unless otherwise there is a force acted upon on the object, that compel it to move in its original position, or to cause to change its direction of motion. This unbalance force cause the vehicle to move in the direction of the applied force.
