Positively charged particles are projected into a magnetic field. If the direction of magnetic field is along the direction of motion of the charged particles, the particles will experience
- A acceleration
- B deacceleration
- C deflection from the path
- D no change in velocity
Answer & Solution
Correct Answer
(D) no change in velocity
Step-by-step Solution
Detailed explanation
\( \vec{F} = q(\vec{v} \times \vec{B}) = 0 \) if \( \vec{v} \parallel \vec{B} \). No change in velocity.
