How is it possible for the angular magnification to be large and, at the same time, for the lateral magnification to be small? Give an example
What will be an ideal response?
The angular mag. is the ratio of ANGULAR size looking through the instrument compared to the angular size without. The lateral magnification is the ratio of the actual size of image compared to that of the object. The two magnifications are comparing different things. As an example: the moon may appear larger (in angle) through a telescope but the image is certainly smaller than the moon itself.

Two equal point charges Q are separated by a distance d. One of the charges is released and moves away from the other due only to the electrical force between them. When the moving charge is a distance 3d from the other charge, what is its kinetic energy?
