. . Find the electric field strength at the surface of the shown sphere with radius of 1.00 × 10−10? ? = 9.00 × 109??2/?2..

. . Which figure has a wrong electric field line?.

. . If the charge of the proton is distributed uniformly over its volume and if the radius of the proton is ?, how much charge will be.

. . Arrange the flux through the shown surfaces from the largest to the smallest. ?? = 8.85 × 10 −12 ?2/??2..

. . Calculate the electric flux through the Gaussian surface shown in Figure ?? = 8.85 × 10 −12 ?2/??2..

. . Two point charges ?1 = − 2.0?? located at ?1 = 6ො? − 2ො? − 5 Ƹ? and ?2 = 8.64 ?? located at ?2 = 8ො? + 2ො? − Ƹ?. What is the force of ?2 on ?1? (? = 9.00 × 109??2/?2).

. . . 4.6 ??/?. From a distance of 10.0 ??, a particle of mass 4.8 ?? and charged to +7.2 ?? is projected with a speed of 4.6 ??/? directly at a large, positively charged conducting plate whose charge density is 3.9 × 10 −3?/?2 (See the figure) How far from the plate does it turn around? ?? = 8.85 × 10 −12 ?2/??2..

. . Two infinite rods, each carrying a uniform charge density ?, are parallel to one another and perpendicular to the plane of the page. (See below.) What is the ratio of the magnitude of the electrical field at ?1 to the magnitude of the electrical field at ?2?.

. . Shown to right is a small sphere of mass 0.25 ? that carries a charge of 9.00 × 102??. The sphere is attached to one end of a very thin silk string 5.0 ?? long. The other end of the string is attached to a large vertical conducting plate that has a charge density of 30.0 ??. What is the angle ? that the string makes with the vertical? ?? = 8.85 × 10 −12 ?2/??2..

. . A proton enters the uniform electric field produced by the two charged plates shown to the right. The magnitude of the electricfield is 4.0 × 105?/? , and the speed of the proton when it enters is 1.5 × 107?/?..
