A 25 Ω resistor and a 100 Ω resistor connected in a circuit with a third resistor of unknown resistance R, a capacitor of unknown capacitance C, and a battery of unknown emf, as shown. After a long time, the potential difference across the 25 Ω resistor is measured to be 4 V. What is the emf of the battery? The battery labeled epsilon is on the right side. Along the top branch is a 25 ohm resistor, and along the bottom branch is a resistor labeled R. On the left side, a capacitor C and 100 ohm resistor form a smaller loop between junctions with the top and bottom wires. The capcitor is to the left of the junctions and the resistor is to the right.

The figure shows three objects (X, Y and Z) that have charges -4q, +q and –q, respectively. The objects are held on a fixed axis positioned shown. The magnitude of the electrostatic force exerted by object Y on object Z is F. What is the magnitude of the net electrostatic force exerted on object Y due to the other two objects? On the left, X of charge negative 4q at position negative a, at center Y of charge positive q at position zero, and on the right Z of charge negative q at position a.
