5. [-/5 Points] DETAILS KATZPSE1 30.P.051. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A uniform electric field of magnitude 136 kV/m is directed upward in a region of space. A uniform magnetic field of magnitude 0.82 T perpendicular to the electric field also exists in this region. A beam of positively charged particles travels into the region. Determine the speed of the particles at which they will not be deflected by the crossed electric and magnetic fields. (Assume the beam of particles travels perpendicularly to both fields.) m/s Submit Answer 6. [-/5 Points] DETAILS KATZPSE1 30.P.073. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A circular coil 18.0 cm in radius and composed of 145 tightly wound turns carries a current of 2.10 A in the counterclockwise direction, where the plane of the coil makes an angle of 15.0 with the y axis (see figure below). The coil is free to rotate about the z axis and is placed in a region with a uniform magnetic field given by B = 1.20 j T. B 0 = 15.0 (a) What is the magnitude of the magnetic torque on the coil? N . m (b) In what direction will the coil rotate? O counterclockwise as seen from the +z axis O clockwise as seen from the +z axis Submit
