Two particles are fixed to an x axis: particle 1 of charge -2.51 × 10-7 C is at the origin and particle 2 of charge +2.51 × 10-7 C is at x2 = 12.6 cm. Midway between the particles, what is the magnitude of the net electric field?

Four point charges have the same magnitude of 3.2 × 10-¹² C and are fixed to the corners of a square that is 6.2 cm on a side. Three of the charges are positive and one is negative. Determine the magnitude of the net electric field that exists at the center of the square.

Point charges of 28.0 µC and 48.0 µC are placed 0.500 m apart. (a) At what point (in m) along the line connecting them is the electric field zero?                         m (from the smaller charge) (b) What is the magnitude (in N/C) and direction of the electric field halfway between them? magnitude ? N/C Direction: towards larger or smaller charge?

Two equal positive charges (10 μC) are arranged at the base of an equilateral triangle of sides 20 cm. What is the electric field at the top vertex of the triangle? What is the direction of the electric field?

Question 3. Three charges are at the corners of an equilateral triangle, as shown in Figure 3. Calculate the electric field at a point midway between the two charges on the x-axis. 7.00 με 0.500 m 60.0° 60.0° 2.00 μC -4.00 μC Figure 3:

One type of electric quadrupole is formed by four charges of magnitude q = 78nC placed at the vertices of a square of side 2a, with a = 25cm. Point P is located at a distance "x" from the center of the quadrupole. For x = 146 cm, determine the magnitude of the electric field at point P. %D 2a Correct Answer: 118.08 ± 1% (N/C)

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?

Three charges are placed along the x-axis: q1 = 3.00 µC at X1 = -20.0 cm, q2 = -5.00 µC at x2 = 10.0 cm, and q3 = 6.00 µC at x3 = 25.00 cm. Determine the magnitude of the electric field at the origin. O 4 69x106 N/C O 2 96x106 N/C O 6 04x106 N/C O 4.31x106 N/C
