WebF = QvB; F is the force acting on the particle (vector) v is velocity of particle (vector) Q is charge of particle (scalar) B is magnetic field (vector) NOTE: this case is for v and B perpendicular to each other otherwise use F = QvB(sin(x)) where x is the angle between v and B. When v and B are perpendicular x=90 deg. so sin(x)=1. WebThe equation is given by F = q v × B or F = qvB sin θ, where q is the charge, B is the magnetic field, v is the velocity, and θ is the angle between the directions of the magnetic field and the velocity; thus, using the definition of the cross product, the definition for the magnetic field is
F = qvB and the Right Hand Rule Example Problems - YouTube
http://www.myliushu.com/ WebThis particle experiences a force with magnitude F = qvB perpendicular to its velocity. A force perpendicular to the velocity results in centripetal acceleration a = F/m = v 2 /r. The particle will move along a circular path. The radius of the circle is r = mv 2 /F = mv 2 /(qvB) = mv/(qB), and the circle lies in a plane perpendicular to B. The ... carachel
