The capacitor plates are fixed on an inclined plane and connected to a battery of emf E. The capacitor plates have plate area a, length l, and the distance between themis d. A dielectric constant K is inserted into the capacitor and tied to mass M by a massless string as shown in the figure Find the value of M for which the slab will stay in equilibriu. There is no friction between slab and plates. |

Answer» `m/2 + (E^2epsilon_0A(k-1))/(2lgd)` `T=MG` And `T=F+sin30^(@)` or `Mg=F+(Mg)/(2)` or `m=(m)/(2)+(F)/(g)=(m)/(2)+(E^(2)epsilonA(K-1))/(2lgd)`
