The plates of a parallel plate capacitor are, not exactly parallel....
The plates of a parallel plate capacitor are, not exactly parallel. The surface charge density therefore:
(a) Is higher at the closer end
(b) The surface charge density will not be uniform
(c) Each plate will have the same potential at each point
(d) The electric field is smallest where the plates are closest
Options
- Aonly a is correct
- Bonly b & c are correct
- Ca & c are correct
- Da, b & c are correct
Correct answer
D. a, b & c are correct
Step-by-step solution
- Since plates are not parallel, the gap varies.
- Surface charge density is higher where plates are closer. (a) correct.
- Hence, surface charge density is not uniform. (b) correct.
- Each plate is a conductor (\rightarrow) entire plate at same potential. (c) correct.
- Electric field is largest where plates are closest, not smallest (\rightarrow) (d) wrong.
