The switch S in the network is kept open. Assume that all the capacitances shown are accurate to two significant figures. What is potential difference V_cd across the open switch S?

• A) 0 V
• B) 40 V
• C) 50 V
• D) 60 V
• E) 70 V

Salt Domes

Geological formations created when masses of salt are forced upward through overlying sediments, often associated with oil deposits.

Sedimentary Rocks

Rocks formed by the deposition and subsequent cementation of mineral or organic particles on the floor of oceans, lakes, or rivers.

Folds

Structures formed by the bending and warping of rock layers due to pressure and heat in the Earth's crust.
