Question

Consider a particle of mass 1 gm and charge 1.0 Coulomb at rest. Now the particle is subjected to an electric field \( E(t)=E_0\sin\omega t \) in the x-direction, where \( E_0=2 \) N/C and \( \omega=1000 \) rad/sec. The maximum speed attained by the particle is

• A. \( 2\text{ m/s} \)
• B. \( 4\text{ m/s} \)
• C. \( 6\text{ m/s} \)
• D. \( 8\text{ m/s} \)

Hint:

For sinusoidal force: \begin{itemize} \item Integrate acceleration. \item Max velocity when cosine = -1. \end{itemize}

Answer 1

The Correct Option is B
