Question

What is the force between a charge of 5 µC and 6 µC when they are spaced 4.5 cm apart?

Two equal but opposite charges, Q = 18e, are separated by a distance d = 5 mm. What is the electric field at the point P, which is a distance x = 22 µm from the positive charge? The two charges and point P are all along a single straight line.

One electron is placed 4.4 cm from a stationary 4e charge. How fast will the electron be traveling when it reaches the stationary charge? You can find the electron charge and electron mass in the front cover of your book.

Consider a point charge generating an electric field. At a distance of 19.7 cm from the charge, the magnitude of the electric field is 7.3 V/m. What is the electric potential at the same distance?

Two parallel plates each with 14 nC of charge stored on them, and an area of 0.142 m². The voltage across the plates is 4 V. What is the space between the places in mm?
