|---|---|
(P) If distance between plates of an isolated capacitor decreases | (1) potential difference across plate is decreased |
(Q) If dielectric is inserted between plates of capacitor whose plates are connected with battery | (2) Capacitance of the capacitor will increase |
(R) If area of plates of an isolated capacitor is increased | (3) Energy of capacitor will increase |
(S) If distance between plates of capacitor is decreased when the capacitor is connected with battery | (4) Force between the plates will decrease |
| (5) None of these |
Options:
Answer:
Solution:
(P) For an isolated capacitor, constant. If distance between plates decreases, capacitance increases.
Since ; as C increases V decreases.
Since energy ; as C increases energy decreases.
Force stays unchanged for an isolated capacitor.
