Q (1) A two winding system has its inductances $ L_{11}=\frac{k_{1}}{x}=L_{22} $ and $ L_{12}=\frac{k_{1}}{x}= $ $ L_{21} $ where $ k_{1} k_{2} $ are constants. Neglect the winding resistance, derive an expression for the electrical force (as a function of $ x $ ) when both the windings are connected to the same voltage source $ v=V_{m} \sin \omega t $. (5M)
