Answer:
d = 1600 m
Explanation:
If car start from rest and accelerates uniformly then the displacement of the car is given as
now we know
now if the same car will accelerate from rest for four times of the previous time interval
then we will have
so the distance will be 16 times more
The electric potential energy of this system of charges will be +1.44 J. Option E is correct.
<h3>What is the electric potential energy ?</h3>Electric potential energy stands for the energy that is required to displace a charge in against an electric field.
Given data;
q₁ = 4. 0 µc
q₂ = -8. 0 µc
D(distance between charges) = 0.2 m
The electric potential energy is found as;
The electric potential energy of this system of charges will be +1.44 J.
Hence,option E is correct.
