Question

The two plates of a parallel plate capacitor are 4mm apart.A slab of dielectric constant 3 and thickness 3mm is introduced between the plates with its faces parallel to them.the distance between the plates is so adjusted that the capacitance of the capacitor becomes 2/3rd of its original value.what is the new distance between the plates?

Answer 1

Answer:

2+2=5

Explanation:

2+2=4

4+5=9

9-(2+2)=5

THEREFORE, 2+2=5
