Question
The picture on the right shows a plate capacitor.
You may assume that the two plates are very
large compared to the separation between the
plates (i.e. you may treat them as 'infinite'
planes).
The plates are charged to +Q, each plate has an
area of A, and the plates are separated by a
distance d. The x-axis in this problem is pointing
from the negative to the positive plate, with the
origin at the negative plate. The electric field at
point 2 has a magnitude of E.

c. No explanations required:
If the mass of the pith ball is increased, the tension in the string will
(i) increase (ii) decrease (iii) stay the same
If the magnitude of the charge of the pith ball is increased, the tension in the string will
(i) increase (ii) decrease (iii) stay the same
