The energy gained by an electron as it is accelerated by an electric field is equal to the work done by the electric field itself, and this is equal to the product between the charge of the electron and the potential difference across which the electron traveled:
(1)
where e is the electron charge, and
is the potential difference between the initial and the final point of the electron, and this is equal to
(2)
where E is the intensity of the electric field and d is the distance covered by the electron. If we substitute (2) into (1), we find a final expression for the energy gained by the electron

Answer:
The time taken for the paint ball to hit the ground is
The distance of the landing point from the tower is
Explanation:
From the question we are told that
The height of the tower is
The speed of the paintball in the horizontal direction is
Generally from kinematic equation we have that
Here u is the initial velocity of the paintball in the vertical direction and the value is 0 m/s , this because the ball was fired horizontally
a is equivalent to
t is the time taken for the paintball to hit the ground
So
=>
Generally the distance of its landing position from the tower is
=>
=>
