Figure shows two parallel plate capacitors with fixed plates and connected to two batteriers. The separation between the plates is the same for the two capacitors. The plates are rectangular in shape with width b and lengths `l_1 and l_2`. The left half of the dielectric slab has a dielectric constant `K_1` and the right half `K_2` Neglecting any friction, find the ratio of the emf of the left battery to that of the right battary for which the dielectric slab may remain in equilibrium

A

`sqrt((K_2-1)/(K_1-1))`

B

`sqrt((K_1-1)/(K_2-1))`
