Two flat circular and concentric loops of different radii and non-zero resistance are placed on a table. The outer loop has a battery and a switch, with a switch that has been closed for some time. Which of the statements below best describes the current I(t) in the inner loop before and immediately after opening the switch?

Initially the current is zero and then it flows counterclockwise after the switch is opened.

Initially the current is clockwise and then it flows counterclockwise after the switch is opened.

Initially the current is zero and then it flows clockwise after the switch is opened.

Initially the current is clockwise and then it flows clockwise for a short time after the switch is opened.

Initially the current is zero and then it flows counterclockwise for a short time after the switch is opened.

Expert Solution

In this question we have to find the direction of induced current in the inner loop just after switch S is opened.

A smooth circular hoop with a radius of 0.600 m is placed flat on the floor. A 0.450-kg particle slides around the inside edge of the hoop. The particle is given an initial speed of 9.50 m/s. After one revolution, its speed has dropped to 4.50 m/s because of friction with the floor. (a) Find the energy transformed from mechanical to internal in the particle—hoop—floor system as a result of friction in one revolution. _____J (b) What is the total...

Consider a spherical capacitor consisting of two concentric spherical shells of radii R1 and R2 that carry surface charge densities of σ0 and –σ0, respectively. The capacitor is filled with a linear but inhomogeneous dielectric whose relative permittivity is a function of distance from the center of the sphere εr = εr (r).
