A charged particle is moving without deflection in a space region where an elec- tric field E = 3.5x102V/m and a magnetic field B = 0.25T act in perpendicular directions.

Calculate the speed of the particle.

An electric field has a surface of 4cm2 and it is in a region of space with a magnetic field B = 2x10−3T orthogonal to it.

Compute the value of the flux of the magnetic field through the circuit.

Magnetic field due to solenoid

Two parallel rails with negligible resistance are 10.0 cm apart and are connected by a 5.00 ohm resistor. The circuit also contains two metal rods having resistances of 10.0 ohm and 15.0 ohm sliding along the rails (Fig. P31.31). The rods are pulled away from the resistor at constant speeds of 4.00 m/s and 2.00 m/s, respectively . A uniform magnetic field of magnitude 0.0100 T is applied perpendicular to the plane of the rails. Determine the current in the 5.00 ohm resistor.
