Question

Assertion : Acceleration of charged particle in non-uniform electric field does not depend on velocity of charged particle.
Reason : Charge is an invariant quantity. That is amount of charge on particle does not depend on frame of reference.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (B)

$\vec{a}=\frac{q\vec{E}}{m}$ as $\vec{E}$ varies so does $\vec{a}$, it does not depend on its velocity.
