Question 1 Sphere 1 + Sphere 2 + Switch As shown above, sphere 1 and sphere 2 are made of metal and connected together by a wire with a switch. While the switch is open, sphere 1 is given a positive total charge (and sphere 2 remains neutral). Then the switch is closed. How does the electric field , at the surface of sphere 1 compare to the electric field By at the surface of sphere 2? O E, is less than Ez O E, is equal to E2 O E, is greater than Ez Question 2 3 V A 3 V battery has metal wires attached to each end. What is the potential difference A Vay = Vy - V, between points 3 and 4? O ov O 1.5 V O 3V O -3VQuestion 3 AVan A battery of voltage A Vat is connected to a parallel plate capacitor as shown above. Then, without breaking any connections, the separation between the capacitor plates is increased from d to 2d. How does the capacitor charge Q change as the separation increases? It's impossible to know for sure. It stays the same. It decreases to half its original value. It increases to double its original value. Question 4 3 AF 5 ALF 3 UF 3 aF 3 OF = 3 AF 4 u.F [b) (c) (d) The figure above shows four different sections of capacitor circuits. Which two have the same equivalent capacitance? O (b) and (d) O (b) and (c) O (a) and (c) O (a) and (d)
