Suppose a charge of -1.60 µC is at the origin and a charge of 3.30 µC is at the point (0, 3.00) m.
(a) Find the electric potential at (4.00, 0) m, assuming the electric potential is zero at infinity. V = 3 . V What is electric potential? What factors affect the size of the electric potential at a particular point?
(b) Find the work necessary to bring a 3.70 µC charge from infinity to the point (4.00, 0) m. W = 4 . J How does the work done on an object relate to its change in electric potential? If necessary, go back and review the conservation of energy relationships.
A well-engineered ski jump is less dangerous than it looks because skiers hit the ground with very small velocity components perpendicular to the ground. What is the slope of the ground in the landing zone
