Question

If someone can answer any/all of these that would be much appreciated!

C. 1. Can an electrically charged object produce an electric force on a neutral object? a. No, never. Coulomb's Law clearly says the force must be zero. b. Yes, but only if the neutral object is moving. C. Yes, if charge distribution in the neutral object is not uniform. This occurs often and naturally produces an attraction. d. Yes, if charge distribution in the neutral object is not uniform. This occurs often and naturally produces a repulsion. 2. What is the difference between a Volt (V) and an Amp (A)? a. They are different names for the same unit. b. They are different units for the same quantity (like minutes & hours both measure time) Volts measure energy and Amps measure electric charge d. Volts measure energy per unit charge and Amps measure the rate at which electric charge flows 3. If an electron moves from a location with high electric potential to low electric potential, what happens to its electric potential energy? a. It increases b. It decreases c. It stays the same d. Not enough information 4. Two capacitors have the same charge, Q, but different capacitances, C. Which one has the most electric potential energy, U? a. The high capacitance one b. The low capacitance one c. They tie 5. How does the direction of current in a wire compare the direction of electrons moving through the wire? a. Same direction b. Opposite direction c. There is no consistent relationship 6. How does the diameter of a wire affect the resistance of the wire? a. Increasing diameter increases resistance b. Increasing diameter decreases resistance There is no relationship between diameter and resistance C.

Answer 1

1. Answer: Option ca). Explanation: Coulomb's Law states that like charges repel and opposite churges atouct, with a force proportional to the product of the charges and inversely proportional to the squure of the distance between them. The net force = kq, 92 ?. Even if a single puzticle object is neytral, there will be no force between them. 2. Answer : Option (d) Explanation : Volts measure potential difference, that is work

done per unit charge energy per unit charge. Given by AVE W Amps measure the gute at which electric charge flows, and that is nothing but the electric current. Given by I = dQ. dt 3. Answer i Option (4) Electrons move from regions of low potential to the regions with high potential. Potential Energy Potential difference x chunge. In that case, potential energy decreuses. In our cuse, electron moves from a location with high electric potential to low electare potential, the potential

differce will be negative. Charge of electron is negative. energy So the Potential will be. Potential Energy E-Potential difference) * (-charged + ve value, That means, potential energy of the election increases. 4. Answer: Option (b). Explanation : Electric potential energy stored in the cupacitoo is given by Q² 20 where Q = charge on capacitor ca cupacitunce of the capacitor. In our cuse both the Capucitor have the same charge

Thut meuns, electric potential energy_stored in the capacitor is inversely_proportional to cupacitance of the capacitor. The cupacitor which has the low capacitance will has the most electric potential energy stored. 5. Answer: Option. (6) Explanation : Election and current move througth the wire in the opposite direction, 6. Answer: Option (b). Explanation : Resistence of the wire is given by B=3 L А where,

S = Desistivity Le length of wire A. area o of wire (Cross - Sectional area) А Td 4 d diameter of wire. .. Resistance R=s. L I d Ra I d² That means. Resistance of the wire is inversely proportional to the square of diameter of wire Therefore, increusing diameter of wire decreases the kesistance.
