A particle with charge -40.0 nC is on the x axis at the point with coordinate x 0. A second particle, with charge -20.0 nC, is on the x axis at x = 0.500 m. There is a point between x = 0 and x = 500 mm where the electric field is zero. Is the electric potential zero at this point?

What is the electric potential at the dot in the figure? The charge on Q1 is 4.00 nC, the charge on Q2 is 5.00 nC and the charge on Q3 is 3.00 nC. The distance between charge Q1 and charge Q2 is 7.00 cm. The distance between Q2 and Q3 is 2.00 cm. 2.80×103 V 2.42×103 V 2.18×103 V 1.00×103 V

A 11.5 nC charge is at x = 0 cm and a -1.5 nC charge is at x= 6.0 cm .At what point or points on the x-axis is the electric potential zero?

A plastic rod has been bent into a circle of radius R = 11.0 cm. It has a charge Q1 = + 5.38 pC uniformly distributed along one-quarter of its circumference and a charge Q2 = -6Q, uniformly distributed along the rest of the circumference (see the figure). With V = 0 at infinity, what is the electric potential (a) at the center C of the circle and (b) at point P, which is on the central axis of the circle at distance D = 6.02 cm from the center? D Q2 (a) Number i -2.2 Units V (b) Number -1.93 Units

A +3.0 nC charge is at x=0cm and a -1.0 nC charge is at x=4cm. At what point or points on the x-axis is the electric potential zero?

Three charges, q1 = 8.50 nC, q2 = 3.50 nC and q3 = -5.00 nC are distributed as shown in Figure 1. Charge q2 is a distance 35.0 µm to the right of charge 9₁ and charge q3 is a distance of 25.0 µm to the right of charge 92. What is the electric potential a distance of 10.0 µm to the right of charge 93? 91 92 93 Note: Your answer is assumed to be reduced to the highest power possible.

A small particle has charge -4.30 µC and mass 1.10x10-4 kg. It moves from point A, where the electric potential is VA = 250 V, to point B, where the electric potential Vg = 940 V is greater than the potential at point A. The electric force is the only force acting on the particle. The particle has a speed of 5.80 m/s at point A.
