A charged particle enters a uniform magnetic field perpendicular to it. The magnetic field

Question

A charged particle enters a uniform magnetic field perpendicular to it. The magnetic field (A) Increases the speed of the particle (B) Decreases the kinetic energy of the particle (C) Changes the direction of motion of the particle (D) Both(1) (3)

Tardigrade Admin · Accepted Answer

Magnetic force vecF perp vecV ⇒ No work is done by magnetic field so speed and kinetic energy cannot be changed by magnetic field but it can deflect the particle

Q. A charged particle enters a uniform magnetic field perpendicular to it. The magnetic field

Increases the speed of the particle

Decreases the kinetic energy of the particle

Changes the direction of motion of the particle

Both(1) & (3)

Magnetic force $F ⊥ V$
$\Rightarrow$ No work is done by magnetic field so speed and kinetic energy cannot be changed by magnetic field but it can deflect the particle
