A particle of mass 0.5 g and charge \(10 \mu \mathrm{C}\) is subjected to a uniform electric field of \(8 \mathrm{NC}^{-1}\). If the particle is initially at rest, the velocity of the particle after a time of 5 seconds is
- A \(5 \mathrm{~ms}^{-1}\)
- B \(0.5 \mathrm{~ms}^{-1}\)
- C \(8 \mathrm{~ms}^{-1}\)
- D \(0.8 \mathrm{~ms}^{-1}\)
Answer & Solution
Correct Answer
(D) \(0.8 \mathrm{~ms}^{-1}\)
Step-by-step Solution
Detailed explanation
For charged particle, \(\mathrm{m}=0.5 \mathrm{~g}, \mathrm{q}=10 \mu \mathrm{c}, \mathrm{E}=8 \mathrm{NC}^{-1}, \mathrm{t}=5 \mathrm{~s}\) \(\therefore\) Acceleration, \(\mathrm{a}=\frac{\mathrm{qE}}{\mathrm{m}}\) \(\therefore \quad\) Velocity after time t is…
