Electrostatics 7 Question 7

7. Two large vertical and parallel metal plates having a separation of $1 c m$ are connected to a DC voltage source of potential difference $X$ . A proton is released at rest midway between the two plates. It is found to move at $45^{\circ}$ to the vertical just after release. Then $X$ is nearly

(a) $1 \times 10^{- 5} V$

(b) $1 \times 10^{- 7} V$

(d) $1 \times 10^{- 10} V$

Show Answer

Solution:

Net force is at $45^{\circ}$ from vertical.

$\begin{aligned} ∴ q E = m g or \frac{q X}{d} = m g ∵ E = \frac{X}{d} \\ or \\ X = \frac{m g d}{q} = \frac{(1.67 \times 10^{- 27}) (9.8) (10^{- 2})}{(1.6 \times 10^{- 19})} \\ \approx 1 \times 10^{- 9} V \end{aligned}$
