An electric field has a constant value of 3.75 x 103 V/m and is directed to the left. The field is the same everywhere. The potential at a point P within this region is 168 V. Find the potential 8.45 x 10-3 m directly above P. .

Which one of the following statements describes the main symptom of farsightedness and the type of lens that corrects it?

In the following circuit, the current through R4 is 0.5 A. Determine the current through R5.  

A system consists of two converging lenses. Lens 1 has a focal length of f1 = 10.0 cm. Lens 2, which is placed to the right of lens 1, has a focal length of f2 = 5.00 cm. The separation between these two lenses is 45.0 cm. The object is placed 15.0 cm to the left of lens 1. What is the final image distance for the system, measured with respect to the converging lens on the right, and what is the nature of the image?

As shown in the figure below, a 7.50 mH inductor is connected in series with a 3.00 Ω resistor. Find the current 4.50 ms after the switch is moved to position 2 to disconnect the battery, if it is initially 10.0 A.
