Apa. A cone with a circular base of radius 1.78 [m] is immersed in a uniform magnetic field of magnitude 1.46 [T] directed 30° as shown. What is the magnetic flux at the cone's lateral surface?

Tira! Consider the paths of two particles and of the same mass and with initial velocity . The particles enter a region of uniform magnetic field as shown in the figure. Given the trajectories of the particles, which of the following statements is TRUE about the charge of the particles?

LF: Net Force. A 1.50 [μC] charge moves with a velocity of 6.00 [m/s] in a region of uniform electric field 13.5 [N/C] and uniform magnetic field 10.5 [T] 9.75 [T] . What is the net force on the charge?

veBe time. An electron enters a region of uniform with a velocity as shown. What is the magnetic force experienced by the electron?

Where do broken magnets go? A bar magnet with orientation of North (N) and South (S) poles as shown is cut into three pieces. The X pole of the middle piece REPELS the Z pole of another bar magnet. What is the polarity of the X and Y poles?

It's complicated. Consider the circuit shown in the figure and assume that the batteries have negligible internal resistances. The 2.00 [Ω] resistor is consuming energy at a rate of 8.00 [W] when the current through it flows as shown. What is the unknown emf ?

Field work. Consider a non-uniformly charged insulating hollow sphere with inner radius and outer radius . The volume charge density of the hollow sphere is given by , where is a positive constant. Anywhere else, the charge distribution is zero. What is the electric field at a distance from the center of the sphere, where ?

Hint: For a sphere with non-uniform charge distribution that depends only on

with .

Capacitor network bonanza. The capacitor network shown is connected to a 49.0 [V] ideal power source. What is the charge at the 0.60 [μF] capacitor? 

Saan ako lulugar? A point charge is placed at the origin, and a second point charge is placed on the -axis at (, 0). You want to place a third point charge somewhere on the-axis. Take as zero the potential energy of the three charges when they are infinitely far apart. Where should you place to make the work done by an external force to assemble the three charges from infinity to their current positions equal to zero?

Cylindrical charge?! A non-conducting hollow cylinder with total charge uniformly distributed and diameter has its axis aligned on the -axis and with bases at to (see figure). What is the net electric field at point (, 0) due to this charge (in integral form)?
