Question 143 of 311

A charged ball B hangs from a silk thread SS which makes an angle θ\theta with a large charged conducting sheet P\mathrm{P}, as show in the figure. The surface charge density σ\sigma of the sheet is proportional to

Show answer and solution

Answer: (D) tan⁡θ\tan \theta



tan⁡θ=qσ(2ε∘)mg\tan \theta=\frac{q \sigma}{\left(2 \varepsilon_{\circ}\right) m g}
