Two 20 kg spheres are fixed in place on a y axis, one at y = 0.40 m and the other at y = −0.40 m. A 10 kg ball is then released from rest at a point on the x axis that is at a great distance (effectively infinite) from the spheres. If the only forces acting on the ball are the gravitational forces from the spheres, then when the hall reaches the ( x , y ) point (0.30 m. 0), what are (a) its kinetic energy and (b) the net force on it from the spheres, in unit-vector notation?

Checkpoint 4
The figure shows four orientations of an electric di-
pole in an external electric field. Rank the orienta-
tions according to (a) the magnitude of the torque
on the dipole and (b) the potential energy of the di-
pole, greatest first.
