A nonuniform electric field is directed along the x-axis at all points in space. This magnitude of the field varies with x, but not with respect to y or z. The axis of a cylindrical surface, 0.80 m long and 0.20 m in diameter, is aligned parallel to the x-axis, as shown in the figure. The electric fields E, and E2, at the ends of the cylindrical surface, have magnitudes of 9000 N/C and 5000 N/C respectively, and are directed as shown. (s0 = 8.85 × 10-12 C2/N•m²) The charge enclosed by the cylindrical surface is closest to 0.20 m E E2 0.80 m- 4.8 nC. O 1.1 nC. -2.4 nC. -4.8 nC. О-1.1 nC.

Two parallel, uniformly charged, infinitely long wires carry opposite charges with a linear charge density λ = 1.00 μC/m and are 4.22 cm apart. What is the magnitude of the electric field at a point midway between them and 44.2 cm above the plane containing the two wires?

A small object of mass 3.54 g and charge −19.3 ?C is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. What are the magnitude and direction of the electric field? magnitude   direction

A proton enters a region of uniform electric field of magnitude 79.9 N/C with an initial velocity of 19.6 km/s directed perpendicularly to the electric field. What is the speed of the proton 2.03 μs after entering this region? O 30.0 km/s O 19.6 km/s O 25.0 km/s O 32.5 km/s O 27.5 km/s

In the figure a uniform, upward electric field of magnitude 1.60 × 103 N/C has been set up between two horizontal plates by charging the lower plate positively and the upper plate negatively. The plates have length L = 17.0 cm and separation d = 1.70 cm. An electron is then shot between the plates from the left edge of the lower plate. The initial velocity of the electron makes an angle 0 = 45.0° with the lower plate and has a magnitude of 6.40 × 105 m/s. (a) Will the electron strike one of the plates? (b) If so, which plate, top or bottom? (c) How far horizontally from the left edge will the electron strike? ↑E 5%8 (a) (b) (c) Number Mr Units <

Inside a vacuum tube, an electron is in the presence of a uniform electric field with a magnitude of 320 N/C. (a). What is the magnitude of the acceleration of the electron (in m/s2)?   m/s2     ?? (b). The electron is initially at rest. What is its speed (in m/s) after 1.15 ✕ 10−8 s? m/s ?

I need help for these questions, I am studying for the physics exam and I couldn't solve this questions which are in the study plan of physics-102. Thanks in advance.
