Q. If the car starts at height h= 3.00 R and the radius is R_1 = 24.0 m, compute the radial acceleration of the passengers when the car is at point C, which is at the end of a horizontal diameter.

Q. A uniform electric field witha magnitude of 250 N/C is directed in the positive xdirection. A 12 uC charge moves from the origin to the point(20.0 cm, 50.0 cm). what is the change in the electricalpotential energy of the system as a result of the change inposition of this charge?
