Question
Consider the three resistors and the battery in the circuit shown. Which resistors, if any, are connected in serial? Answer _____ f) R_2 and R_1 g) R_2 and R_3 h) R_1 and R_3 i) R_1 and R_2 and R_3 j) This cannot be determined In the diagram, the current in the 3-Ohm resistor is 2 A. The potential difference between points 1 and 2 is: Answer _____ A) 7.5 V B) 8 V C) 15 V D) 10 V E) 20 V A negatively-charged particle travels parallel to magnetic field lines within a region of space. Which one of the following statements concerning the force exerted on the particle is true? Answer _____ a) The force is directed perpendicular to the magnetic field. b) The force is perpendicular to the direction in which the particle is moving. c) The force slows the particle. d) The force accelerates the particle. e) The force has a magnitude of zero newtons.Explanation / Answer
13)There isn't any correct option among given alternatives.This because resistors R2 and R3 are parallel and their equivalent is in series with resistor R1.
14) D
current is equal in serial resistors.So voltage equals net resistance multiplied by current.(ohms law)
15)e
Since velocity of charged particle is parallel to magnetic field, no force acts on it.This conclusion is in accordance with definition of magnetic force on charged particle.
