Physics Lab Write Up Questions: 1. Derive the final expression from the theory section using torque instead of force. 2. What is the net force on the wires in the balance that run parallel to the solenoid? 3. Devise another way to run this experiment without using a mass on the other end of the […]
Describe how electric potential energy, kinetic energy, and work change when two charges of opposite sign are placed near each other.
Physics Electricity and Magnetism Question 1 (4 points) Make a drawing of the electric field lines around a positive charge, then make a second drawing of the electric field lines around a negative charge. (1 point) What is the mathematical equation for the electric force between two charges? Identify each variable. (1 point) Describe the […]
Find the speed and direction of the wire’s motion as a function of time, assuming it to be stationary at t = 0. Evaluate for t = 0.5 s.
PROMPT A metal wire of mass m = 0.400 kg slides without friction on two horizontal rails spaced a distance d = 0.40 m apart, as in the figure. The track lies in a vertical uniform magnetic field B = 0.50 T. There is a constant current i = 0.35 A through generator G, along […]
What is the magnitude and direction of the magnetic field vector due to the long, straight wire at the location of the electron?
Magnetic field and current related questions An initially uncharged capacitor with a capacitance of C= 00 pF is connected in series with resistor with a resistance of R= 4.5 kn. If this series combination of circuit elements is attached to an ideal battery with an emf of f= 450 V by means of a switch […]
