There is a +8.7 µC point charge at the origin and a -9.7 µC point charge at coordinates (5.0 cm, 0, O). At what x-coordinate on the x-axis outside of the two charges (i.e., less than 0 or greater than 5.0 cm) is the net electric potential zero (relative to very far away from the charges)?

A 4 = 6.00 µC point charge is at the origin, and another point charge 92 = -3.00 µC is on the x-axis at (3.00, 0) m, as in Figure. If the electric potential is taken to be zero at infinity, find the total electric potential due to these charges at point P with coordinates (0, 4.00) m. у (m) P (0, 4.00) 12 х (m) (3.00, 0)

In the figure particles with charges q1 = +2e and q2 = -15e are fixed in place with a separation of d = 23.0 cm. With V = 0 at infinity, what are the finite (a) positive and (b) negative values of x at which the net electric potential on the x axis is zero? (a) Number i (b) Number i Units Units 91 + + 92

A line of charge with a non-uniform charge density λ (lambda) = ay, where a=−10 nC/m2 lies along the y axis with one end at the origin and the other at y=h, where h=4.7 m Given that the total charge is -110.45 nC, calculate the electric potential of this line of charge at point P on the x axis a distance 0.7 m from the origin. Assume the potential equals zero at infinity

Two charges are located along the x-axis. A positive charge 15.1 uC is at x-0, and a negative charge -2 uC is located at x-10.8 m. Point P is located somewhere between the two charges such that the electric potential due to the two charges is zero, Point P is at x m.

A line of charge with a non-uniform charge density λ=ay, where a=−10 nC/m2 lies along the y axis with one end at the origin and the other at y=h, where h=0.5 m. What is the total charge? What is the electric potential of this line charge at point P?

The figure shows a rectangular array of charged particles fixed in place, with distance a = 33.7 cm and the charges shown as integer multiples of q1 = 3.32 pC and q2 = 7.25 pC. With V= 0 at infinity, what is the net electric potential at the rectangle's center?

The electric field 2.5 cm from an unknown charge has a strength of 428 N/C and points toward the charge. (a) What then is the electric potential at that distance, assuming there are no other point charges in the region? Vp = 428 x V (b) The electric field strength at a different point near another charge is 315 N/C. How far is this point from the charge if the electric potential there is -33 V? d = cm

In the figure a charged particle (either an electron or a proton) is moving rightward between two parallel charged plates separated by distance d = 3.60 mm. The plate potentials are V₁ = -63.0 V and V₂ = -45.0 V. The particle is slowing from an initial speed of 83.0 km/s at the left plate. (a) Is the particle an electron or a proton? (b) What is its speed just as it reaches plate 2? (a) (b) Number i Units

Two identical point charges, each of 2.0 nC are held fixed on the x-axis, one at x= -3.0 cm, y =0 and the other at x = +3.0 cm, y= 0. In what follows, the electric potential is taken to be zero at infinity.   Calculate the electric potential VA at location A of coordinates x = 0, y= +4.0 cm, and the electric potential VB at location B of coordinates x = 0, y = 0 (the origin).  An electron is released from rest at location A and immediately starts moving along the y axis towards location B. Use conservation of energy to calculate the speed of the electron when it reaches location B.
