A) 2.0 N B) 4.0 N C) 16 N D) 1/4 N E) 1/16 N Question 2 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? Question 3 Water is present on the Moon and Mercury in the form of A) liquid water present just beneath the surface B) ice in polar craters C) vapor in the atmosphere D) oceans of liquid water on the surface Question 4 What is the power output of a hot air furnace that produces heat at the rate of 160,000. BTU/hr? A) 22 kW B) 80 kW C) 47 kW D) 7.6 kW E) 1.6 kW Question 5 An organism with an Encephalization Quotient (EQ) of 1 is expected to be of A) above-average intelligence B) average intelligence C) the lowest possible intelligence D) below-average intelligence Title: Two point charges, initially 2.0 cm apart, experience a 1.0-N force.

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.
