Charge Q is uniformly distributed along a thin, flexible rod of length L. The rod is then bent into the semicircle shown in the figure (Figure 1).Part AFind an expression for the electric field \(\vec{E}\) at the center of the semicircle. Hint: A small piece of arc length \(\Delta s\) spans a small angle \(\Delta \theta=\Delta s / R,\) where R is the radius.Express your answer in terms of the variables Q, L, unit vectors \(\hat{i}, \hat{j},\) and appropriate constants.Part BEvaluate the field...

A small electrically charged bead with the mass m and charge Q can slide on a circular insulating string without friction. The radius of the circle is r. A point-like electric dipole is at the center of the circle with the dipole moment P lying in the plane of the circle. Initially the bead is at an angle θ = 플 +6, where δ is infinitely small, as shown schematically in the figure below. Figure 3: Bead on a string...

1 Review Part A High-frequency signals are often transmitted along a coaxial cable, such as the one shown in the figure. For example, the cable TV hookup coming into your home is a coaxial cable. The signal is carried on a wire of radius ri while the outer conductor of radius r 2 is grounded. A soft, flexible insulating material fills the space between them, and an insulating plastic coating goes around the Find...

Problem 4 Two identical small spheres with mass, m, are hung from a very thin string of length L, as shown in figure (17.56). The radius of the spheres is small and we can treat the spheres as point like objects. The charge on each sphere is q. Determine the angle, θ, each string makes with the vertical direction. Assume that the angle is small, (Hint: when θ is small you can use that θ sin θ tan θ) mass...
A uniform flexible chain of length L, with mass per unit length A, passes over a small (radius is negligible), frictionless pulley, as shown in figure 1. One side of the chain with length x is tied to a block with mass m. The chain and block are released
A uniform flexible chain of length L, with mass per unit length
A, passes over a small (radius is negligible), frictionless pulley,
as shown in figure 1. One side of the chain with length x is tied to
a block with mass m. The chain and block are released from a
rest position at t = 0 s. (Hint: the chain can be treated as a rope
