Expert Answer
Recall that V = Ed
For the capacitor with plates whose separation is increased by 2mm, the potential difference can be written as
V = E0d + (E0/K)x -----(1)
Here d = 4mm the original distance between the plates. x = 2mm the further increase in distance.
E0 = V/d , in the question both V and d are given so find E0
Use this value in eq.1 with V = 100V and putting in all other values find K
