Question

Two point charges, Q1 and Q2, are separated by a distance R. If the magnitudes of both charges are doubled and their separation is also doubled, what happens to the electrical force that each charge exerts on the other one? Two stationary point charges q1 and q2 are shown in the figure along with a sketch of some field lines representing the electric field produced by them. What can you deduce from the sketch? If a charege generator builds a negative static charge of -12.00 muC, how may elctrons are transferred to if during this process The electic field at a point 1.8 cm from a small object ponts toward the object with a strength of 180.000 N/C. What is the object's charge q? Apair of charged conducting plates produces a uniform field of 12,000 N/C, directed to the right, between the plates. The separation of the plates is 40 mm. An electron is projected from plate A, directly toward plate B, with an initial speed of v0 = 2.0 times 107 m/s. What is the speed of the electron as it strikes plate B?
