Two large parallel copper plates are 7.39 cm apart and have a uniform electric field of magnitude E = 3.44 N/C between them (see the figure). An electron is released from the negative plate at the same time that a proton is released from the positive plate. Neglect the force of the particles on each other and find their distance from the positive plate when they pass each other. Positive Negative plate plate E Number i Units

Two 3.7-g spheres are suspended by 13.5-cm-long light strings (see the figure). A uniform electric field is applied in the x-direction. If the spheres have charges of -4.5 x 10-8 C and +4.5 x 10-8 C, determine the electric field intensity that enables the spheres to be in equilibrium at 8 16°. N/C Ē @ A

View Policies Current Attempt in Progress A capacitor is constructed of two concentric conducting cylindrical shells. The radius of the inner cylindrical shell is 2.35 x 103 m, and that of the outer shell is 2.47 x 10 m. When the cylinders carry equal and opposite charges of magnitude 2.0 x 10 10 C, the electric field between the plates has an average magnitude of 3.9 x 10 V/m and is directed radially outward from the inner shell to the outer shell. Determine (a) the magnitude of the potential difference between the cylindrical shells and (b) the capacitance of this capacitor. +] Cylindrical capacitor (end view)

A parallel-plate capacitor is formed from two 5.8 cm -diameter electrodes spaced 1.9 mm apart. The electric field strength inside the capacitor is 1.0 ×106N/C. What is the charge (in nC) on each electrode?

*Chapter 22, Problem 030 GO The figure shows two concentric rings, of radiiR and R' = 2.34R, that lie on the same plane. Point P lies on the central z axis, at distance D = 3.15R from the center of the rings. The smaller ring has uniformly distributed charge Q = 6.84 x 10° °C. What is the uniformly distributed charge on the larger ring if the net electric field at P is zero? Number 1 Units

A parallel-plate capacitor has a charge Q and plate separation d, as shown below. We assume that the size of plates is much larger than the separation d. Each particle is initially at rest and then released, allowing it to accelerate.  Assuming each particle has the same mass, rank the speeds of the particles when they impact the left plate. 1.
