Question

In part (a) of the figure an electron is shot directly away from a uniformly charged plastic sheet, at speed vs = 3.40 × 105 m/s. The sheet is nonconducting, flat, and very large. Part (b) of the figure gives the electron's vertical velocity component v versus time t until the return to the launch point. What is the sheet's surface charge density?
Assume ts = 26.0 ps.

In part (a) of the figure, an electron is shot directly away from a uniformly charged plastic sheet at speed \( v_s = 3.40 \times 10^5 \, \text{m/s} \). The sheet is nonconducting, flat, and very large. Part (b) of the figure gives the electron's vertical velocity component \( v \) versus time \( t \) until the return to the launch point. What is the sheet's surface charge density? Assume \( t_s = 26.0 \, \text{ps} \). **Diagram Analysis:** - **Diagram (a):** - Shows an electron (\(-e\)) being projected upward away from a horizontally oriented charged sheet. - The electron's velocity is directed perpendicularly to the surface of the sheet. - **Graph (b):** - The vertical axis represents the electron's velocity \( v \) in units of \( 10^5 \, \text{m/s} \). - The horizontal axis represents time \( t \) in picoseconds (ps). - The graph is a straight line decreasing from \( v_s \) to \( -v_s \) over a timeframe of \( t_s = 26.0 \, \text{ps} \). - This indicates a uniform change in velocity, characteristic of constant acceleration. **Input Fields:** - A numerical field to enter the calculated surface charge density. - The units for the surface charge density are given as \( \text{C/m}^2 \). **Given Answer:** - The provided value for the surface charge density is \( 1.316 \times 10^{-6} \, \text{C/m}^2 \).
