The equation of the tangent line is
E) y=−4x−8
Answer:
0.018 J
Explanation:
The work done to bring the charge from infinity to point P is equal to the change in electric potential energy of the charge - so it is given by
where
is the magnitude of the charge
is the potential difference between point P and infinity
Substituting into the equation, we find
- Initial velocity=0m/s=u
- Acceleration=a=5.5m/s^2
