Paralel Levhalar Arasında Denge

5. Birbirine paralel yüklü iletken levhalar arasına asılan kütlesi m, yükü q olan noktasal bir cisim şekildeki gibi dengededir.

Levhalar arasında oluşan elektriksel alan E olduğuna göre, cismin q yükü, aşağıda verilen bağıntılardan hangisiyle hesaplanır?

(g: yer çekimi ivmesidir.)

A) $ \frac{E}{m \cdot g} $

B) $ m \cdot g \cdot E \cdot d $

C) $ \frac{m \cdot g \cdot d}{E} $

D) $ \frac{m \cdot g}{E} $

E) $ \frac{m \cdot g}{E \cdot d} $

Soruda görsel içerik var: The image shows two vertical parallel plates, separated by a distance 'd'. The left plate is positively charged ('+') and the right plate is negatively charged ('-'). An electric field vector 'E' points from the positive plate to the negative plate. A small point mass 'm' with charge 'q' is hanging from a silk thread attached to the ceiling between the plates. Due to the electric field, the thread makes a 45-degree angle with the vertical. The force components acting on the object include its weight (mg) acting downwards and the electric force (F = qE) acting horizontally towards the right (positive x-direction).
