A 1.5 kg metal rod is placed on two conducting rails that are 1.7 m apart.  The rails are inclined at a 30° from the horizontal as shown on the figure below. There is a 30.0 T magnetic field that is perpendicular to the conducting rails as shown above.  Completing the loop is a 200 Ω resistor. Assume the bar starts from rest and slides with negligible friction.   a.) Draw a free-body diagram of bar as it slides down the conducting rails (1 point). b.) Eventually the bar reaches a constant final speed.  What is the current through the resistor when the bar has reached its constant final speed (1 point)? c.) What is the final speed of the bar (1 point)? d.) What is the power of the resistor when the bar is at final speed (1 point)? e.) Determine an expression for the speed of the bar as a function of time t if t = 0 at the moment the bar is released (2 points).

A pаrаllel plаte capacitоr that is initially uncharged has an area оf 0.20 m2. The twо plates are separated by 0.5 cm and connected to a 12 V battery.  What is the maximum charge stored on the capacitor if the dielectric between the two plates is air (kair = 1)?

A quarter circle of radius 50 cm has a +300 μC charge distributed uniformly as shown below.  The origin of the x-y axis is also the center of the circle and has a coordinate of (0,0).  a.) How does the electric potential at point B compare that the electric potential at point A.  Justify your response. (1 point) b.) What is the electric potential at the origin of the x-y axis? (1 point) c.) A proton (mass = 1.67 x 10-27 kg and charge = 1.6 x 10-19 C) starts from rest at the origin of the x-y axis.  What is the speed of the proton when it is very far away from its initial position? (1 point)  d.) On the diagram below, draw the direction of the electric field at the origin of the x-y axis. (1 point) e.) What is the magnitude of the electric field at the origin? (2 points)
