The charged particle goes unaccelerated i.e net force = 0 vec(F) = vec(F)(e) + vec(F)(m) = qvec(E) + qvec(v) xx vec(B) = 0 vec(E) = -(vec(v) xx vec(B)) i.e. vec(E) is |^(ar) to vec(v) as well as vec(B) |vec(E)| = |-vec(v) xx vec(B)| rAr...
*11 The diagram shows the track of a charged particle in a magnetic field. The field is at right angles to the plane of the paper and its direction is out of the plane of the paper.AB is a thin sheet of lead that the particle passes through.A PQ B Work out the direction of movem...
30 A charged particle is in the electric field between two horizontal metal plates connected to a source of constant potential difference, as shown. There is a force F on the particle due to the electric field.charged particle The separation of the plates is doubled.What will be the new fo...
A charged particle beam exposure system checks for the shape of the charged particle beam shaped by a mask by causing a scanning of a marker pattern provided on a substrate along a scanning path. The reflected electrons emitted from the substrate are detected, and the shape of the charged ...
An accelerating electrode system for ionic propulsion systems consists of ribbons of a material (copper, for instance) whose disintegration under ion bombardment would not impair the operation of the W emitter. A system for detecting sputtering would actuate a motor arrangement that would move fresh ...
A charged particle carrying charge 1μC is moving with velocity (2ˆi+3ˆi+4ˆk)ms−1. If an external magnetic field of (5ˆi+3ˆj−6ˆk)×10−3T exists in the region where the particle is moving then the force on the particle is →F×10−9N. The vector →F ...
In a magnetic field, the force on a moving charged particle is maximum when the particle moves ___. A. parallel to the magnetic field B. perpendicular to the magnetic field C. at an angle of 45 degrees to the magnetic field D. in any random direction 相关...
27 A negatively charged particle enters a region of uniform magnetic field. The direction of the magnetic field is into the plane of the paper as shown in the diagram below.X X X X region of uniform magnetic field charged particle Which of the following diagrams correctly shows the path of...
1 So, if we think about the force that occurs between a positively and a negatively charged particle, what we have is essentially a Coulomb force, so we can describe this as a force of attraction.一个带负电的粒子之间，的作用力，这本质上就是库伦力，我们可以把它，描述成一个引力...
