Question
Positively charged particles are projected into a magnetic field. If the direction of the magnetic field is along the direction of motion of the charged particles, the particles getAcceleratedDeceleratedDeflectedNo change in velocity
Solution
No change in velocity
Explanation: The force exerted by a magnetic field on a moving charged particle is given by the equation F = qvBsinθ, where F is the force, q is the charge, v is the velocity, B is the magnetic field strength, and θ is the angle between the velocity and the magnetic field. If the direction of the magnetic field is along the direction of motion of the charged particles (i.e., θ = 0 degrees), then sinθ = 0, and therefore F = 0. This means that the magnetic field does not exert any force on the particles, so their velocity does not change.
