If the inductance in an LC circuit is doubled and the capacitance is halved, what happens to the angular frequency?

Question 10
Physics C: E&M (2025)APConcept Practice
1 mark

An LC circuit needs to be designed to oscillate at a specific angular frequency ω0\omega_0ω0​. Due to budget constraints, the total cost of the inductor and capacitor must be minimized. If the cost of the inductor is proportional to its inductance (CostL=kLCost_L = kLCostL​=kL) and the cost of the capacitor is proportional to its capaci...
