In the figure area of each plate is A and the distance between consecutive plates is as shown in the figure. What is the effective capacitance between points A & B.

(a) `(Aepsilon_(0))/(d)`
(b) `(3A epsilon_(0))/(d)`
(c) `(2A epsilon_(0))/(d)`
(d) `(4 A epsilon_(0))/(d)`

A

`(Aepsilon_(0))/(d)`

B

`(3A epsilon_(0))/(d)`

C

`(2A epsilon_(0))/(d)`

D

`(4 A epsilon_(0))/(d)`

Text Solution

Verified by Experts

The correct Answer is:
A, B, D

`C_(1)= (epsilon_(0)A)/(2d)`
`C_(2) = (epsilon_(0)A)/(d)`
`C_(3)= (in_(0)A)/(2d)`
`C_(eq)=(in_(0)A)/(d)+(in_(0)A)/(2d)+(in_(0)A)/(2d)=(2 in_(0)A)/(d)`

A charged metallic sphere A is suspended by a nylon thread. Another charged metallic sphere B held by an insulating handle is brought close to A such that the distance between their centres is 10 cm, as shown in figure (a). The resulting repulsion of A is noted (for example, by shining a beam of light and measuring the deflection of its shadow on a screen). Spheres A and B are touched by uncharged spheres C and D respectively, as shown in figure (b). C and D are then removed and B is brought closer to A to a distance of 5.0 cm between their centres, as shown in figure (c). What is the expected repulsion of A on the basis of Coulomb's law ? Spheres A and C and spheres B and D have identical sizes. Ignore the sizes of A and B in comparison to the separation between their centres.
