An electric dipole consisting of charges of magnitude 1.4NC separate by 6.23uc ,is in an electric field of strength 1100N/C.(a) what is the magnitude of the electric dipole moment?(b) what is the difference in potential energy corresponding to dipole orientation parallel and anti parallel to the field

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
