Question
Identical dielectric slabs are inserted into two identical capacitors A and B. These capacitors and a battery are connected as shown in figure. Now the slab of capacitor B is pulled out with battery remaining connected :
- During the process, charge flows from a to b.
- Finally charge on capacitor B will be less than that on capacitor A
- During the process, a work is done by the external force F, which appears only as heat in the circuit.
- During the process, internal energy of the battery does not change.
The correct answer is: During the process, internal energy of the battery does not change.

A narrow monochromatic beam of light of intensity I is incident on a glass plate as shown in figure. Another identical glass plate is kept close to the first one and parallel to it. Each glass plate reflects 25% of the light incident on it and transmits the remaining. Then the ratio of the maximum to minimum intensities in the interference pattern formed by the two beams obtained after one reflection at each plate is
