how can this include static forces? Is there a generally accepted way to argue in detail how to get from this to the static case? If not, what different solutions are discussed?
Two point charges nC and nC are 0.100 m apart. Point A is midway between them and point B is 0.080 m from and 0.060 m from . Take the electric potential to be zero at infinity.
(a) Find the potential at point A.
(b) Find the potential at point B.
(c) Find the work done by the electric field on a charge of 2.50 nC that travels from point B to point A.
An antelope moving with constant acceleration covers the distance between two points 70.0 m apart in 6.00 s. Its speed as it passes the second point is 15.0 m/s. What are (a) its speed at the first point and (b) its acceleration?
