Correct Answer - Option 2 : qE/m
The correct answer is option 2) i.e. qE/m
CONCEPT:
- The electric field is defined as the electric force per unit charge.
- A stationary charge q placed in an electric field intensity of E will experience an electrostatic force (F) given by
F = qE
EXPLANATION:
- If a particle of mass m accelerates, from Newton's second law we know that the force experienced by this particle, F = ma
- For a charged particle the force experienced, F = qE
Therefore, qE = ma
⇒ Acceleration (a) = qE/m
