    E After a long time, the current through the branch containing the inductor increases to its maximum value. The current provided by the source, , splits at the junction leading to the parallel combination. The amount which flows through the inductors is half the total. A Once the switch is opened, the resistor r is cut off from the circuit, so no current passes through it. Current will flow around the loop containing the resistors labeled R, gradually decreasing until the energy stored in the inductor is exhausted. Since points X and Y are at the same distance from the center of the sphere, the electric field strength at Y will be the same as at X.

  • Module 2 'Dynamics' Practice Test | Year 11 Physics

    B First determine the electric potential at Point P. Realize that Point P is 5 meters away from each charge because it is a right triangle. The work done by the electric field will be positive because a —Q charge would be attracted to point P by the two positive Q charges. Also the work done by the force is the negative of the change in potential energy. Answer choices A and C can be eliminated because they give negative results. This leaves only answer choice E satisfying the given conditions.

    D Since the magnetic flux out of the page is decreasing, the induced current will oppose this change as always , attempting to create more magnetic flux out of the page. In order to do this, the current must circulate in the counterclockwise direction remember the right-hand rule. D Treat the configuration as three capacitors in series, each with a distance between the plates of. The capacitance of the two vacuum capacitors will be , and the capacitance of the dielectric capacitor will be that value times K. Now solve for the total capacitance for the three capacitors in series. A The potential is zero at the point midway between the charges, but nowhere is the electric field equal to zero except at infinity.

    Statement III is also false: The equipotentials in the plane of the page are not ellipses with the source charges as foci. That is, the point on the z-axis where the potential due to the ring is greatest is at the center of the ring. As it moves along the z-axis, the force will decrease, so it will move with increasing speed and decreasing acceleration away from the origin. We are asked to find the time t at which b i Once the switch is turned to position 2, the capacitor discharges through resistor R only. This change in magnetic flux induces an emf. By the right-hand rule, then, current must flow from Y to X. The following diagram which is a side view of the apparatus looking at the X end of the strip, shows that the force the strip feels parallel to the rails and upward is The net force on the strip is zero when these two opposing forces balance; the speed at which this occurs will be denoted vf: c The rate at which thermal energy is produced in the strip is I2R.

    There is a heavy emphasis on both mathematical and conceptual understanding of these concepts, as most topics will carry forward into future physics courses or practical applications. The material covered in AP Physics B is heavily centered in mechanics, including one- and two-dimensional motion, but it also branches into electrical circuits, electrostatics, optics, and thermodynamic. This exam consists of two sections: multiple-choice and free-response. The multiple-choice section consists of 70 questions, most of which are independent.

The next largest section of the exam consists of electrical concepts, and a basic introduction to magnetism. Students should be extremely familiar with circuits and have a decent understanding of electric and magnetic fields and forces. The final topics of the AP Physics B exam are optics, waves, and quantum theory. Test-takers should have a good understanding of mirrors and lenses, as well as the relationships between wavelength, frequency, and other wave properties.
