Dr. Huerta Phy 102 Test 1 ANSWER KEY Form 1 7 February 2005 [1.] Avogadro’s number of electrons have a charge of 9 . 65 × 10 4 C, called one faraday. About how long would a 10 A current have to ﬂow to transport that much charge? [A] 1.4 hours [B] 9 . 65 × 10 3 hours [C] 27 hours [X] 2.7 hours [E] 10 - 6 seconds [2.] Two point charges q 1 = Q and q 2 = 9 Q are separated by a distance L . A charge located on the line between them is in equilibrium when its distance from q 1 is [A] L [B] L/2 [C] L/3 [X] L/4 [E] There is no equilibrium position. [3.] A 10 A current enters the (+) terminal of a device, passes through the device across a potential diﬀerence of 240 V and exits at the (-) terminal. This device [A] generates 2400 W [B] generates 24 W [X] consumes 2400 W [D] consumes 24 W [E] generates 250 W [4.] Four equal charges are located at the corners of a square of side L . If the magnitude of each charge is doubled, then what happens to the resultant force on each charge? [A] It is doubled.
