What is the magnitude of acceleration of an electron in a uniform electric field of (3.70x10^1) N/C ? The answer should be in m/s2 to 3 significant figures.

Three charged particles are at the corners of an equilateral triangle as shown in the figure below. (Let q = 2.00 μC, and L = 0.550 m.) q: 7.00 με y 60.0° L 9 - x -4.00 μC (a) Calculate the electric field at the position of charge q due to the 7.00-μC and -4.00-μC charges. Once you calculate the magnitude of the field contribution from each charge you need to add these as vectors. KN/C 1 + Does the -4.00-μC charge contribute to the y component of the field at the origin? KN/C ĵ (b) Use your answer to part (a) to determine the force on charge q. If you know the electric field at a particular point, how do you find the force that acts on a charge at that point? mN I + Check units carefully. Note that the field in part (a) is given in kN/J and the force in this part is given in mN. mNĵ x

Two particles are fixed to an x axis: particle 1 of charge q1 = 2.12 × 10-8 C at x = 25.0 cm and particle 2 of charge q2 = -4.84q1 at x = 72.0 cm. At what coordinate on the x axis is the electric field produced by the particles equal to zero?

In this example, we will analyze the motion of an electron that is released in an electric field. The terminals of a 100 V battery are connected to two large, parallel, horizontal plates 1.0 cm apart. The resulting charges on the plates produce an electric field E in the region between the plates that is very nearly uniform and has magnitude E = 3.0×104 N/C. Suppose the lower plate has positive charge, so that the electric field is vertically upward, as shown in (Figure 1). (The thin pink arrows represent the electric field.) If an electron is released from rest at the upper plate, what is its speed just before it reaches the lower plate? How much time is required for it to reach the lower plate? The mass of an electron is mẹ = 9.11 x 10-31 kg. The thin arrows represent the uniform electric field. 1.0 cm 100 V In this example, suppose a proton (mp = 1.67 × 10-27 kg) is released from rest at the positive plate. What is its speed just before it reaches the negative plate? Express your…

hello,  Two-point charges q1 and q2 both have a charge equal to +6.0 nC and are on the y axis at y1=+3.0 cm and y2=−3.0 cm, respectively. What are the magnitude and direction of the electric field on the x axis at x=4.0 cm?

The visible portion of a lightning is preceded by an invisible stage in which a column of electrons moves from a cloud to the ground. The linear charge density λ along the column is typically -1 x 10-3 C/m. If air molecules are ionized in an electric field exceeding 3 x 106 N/C, what is the radius of the column?

Two 8.00 μC charged particles are located on the x axis. One is at x = 1.00 m, and the other is at x = -1.00 m. (a) Determine the electric field on the y axis at y = 0.400 m. N/CI+ N/C j (b) Calculate the electric force on a -3.00 μC charge placed on the y axis at y = 0.400 m. Ni+ Nj
