The false statements are
E and Fe are parallel to each other, whereas B and Fm are
perpendicular to each other.
When a charged particle is moving along the electric field both the
electric and magnetic fields are acting in parallel.
Both Fe and Fm can perform work
Fe is definitely perform work however Fm is not perform any
work.

Question 10 2 points Save Answer Which of the is NOT true about the magnetic force? The magnetic force is proportional to the speed of the particle. When a charged particle moves parallel to the magnetic field vector, the magnitude of the force on the charge is zero. The magnetic force is perpendicular to the plane formed by ū and B. If the velocity vector makes an angle o with the magnetic field, the magnitude of the magnetic force is...

Which among the following statements is CORRECT? The direction of the magnetic force on a charged particle moving in a magnetic field is always perpendicular to the plane formed by the velocity and magnetic field vectors If the current through a wire placed in a magnetic field doubles, then the magnetic force on the wire quadruples. The direction of the magnetic force on a charged particle moving in a magnetic field is always in the same plane as the velocity...
Which property is observed when a beam of charged particles is fired into a magnetic field?...
Which property is observed when a beam of charged particles is fired into a magnetic field? If the beam of charged particles is parallel to the magnetic field, no deflection will occur. The maximum deflection happens when the beam is perpendicular to the magnetic field. The magnitude of the magnetic deflecting force is directly proportional to the magnitude of the charge on each particle. The magnetic deflecting force is always perpendicular to the direction of travel of the charge and...

Question 3 (#859685) Equipotential Lines) Which of the following statements is NOT true about equipotential lines? Select the correct answer O All points on an equipotential line are at the same voltage. A positively charged particle loses potential energy as it moves from one equipotential line to another equipotential line of a lower voltage. Your Answer Equipotential lines run perpendicular to the electric field lines on a 2- dimensional surface. For a charged particle on an equipotential line, there is...

Suppose that a region with a uniform magnetic field B also has a uniform electric field E perpendicular to the magnetic field, an arrangement called crossed fields. Show that for a charged particle moving in such crossed fields in a direction perpendicular to both E and B, the electric force cancels the magnetic force, provided the particle has a speed v= E/B If the magnetic field is in the vertical upward direction and the electric field is in the northward...
