NEET Physics Question - Capacitors - Parallel Plate Capacitor

Assertion (A): If one plate of a charged parallel plate capacitor is dipped in water and other plate is above it, then water level will rise in capacitor.

Reason (R): Total charge on plates increases.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

When one plate of a charged capacitor is dipped in water, water acts as a dielectric. The force on the dielectric (water) pulls it into the capacitor, causing the water level to rise. The capacitor is disconnected, so the total charge \( Q \) on the plates remains constant. Therefore, (R) is false, but (A) is true.
