Fundamentals of Electricity
The electric field at one face of a parallelepiped is uniform over the entire face and is directed out of the face. At the opposite face, the electric field is also uniform over the entire face and is directed into that face (see Fig. 3). The two faces in question are inclined...

Consider the collisions between a car and a truck whose weight is much heavier than the car (M ≫ m). Friction is so small that it can be ignored. If they are both moving at the same speed when they collide, what best describes the size (or magnitude) of the forces ...
