Answer:
The electric potential will be "259.695 volt".
Explanation:
In the given question, the figure is not provided. Below is the attached figure given.
Given:
Now,
At point P, the electric potential will be:
⇒
By putting values, we get
The distance covered is 54.0 m
Since the motion of the car is a uniformly accelerated motion, we can use the following suvat equation:
where
u is the initial velocity
t is the time
a is the acceleration
s is the distance covered
For the car in this problem, we have
u = 0 (it starts from rest)
is the acceleration
t = 3.9 s is the time
Substituting, we find s:
