A charge is accelerated from rest through a potential difference V and then enters a uniform magnetic field oriented perpendicular to its path. The field deflects the particle into a circular arc of radius R. If the accelerating potential is tripled to 3V, what will be the radius of the circular arc? O R/ SQRT (3) O 9R O 3R O SQRT (3) * RYou cannot use the Bernoulli's equation if the pressure given at two points is in terms gauge pressure. 0 True 0 False Three particles travel through a region of space where the magnetic field is out of the page, as shown in the figure. The electric charge of each of the three particles is, respectively, O 20 O O a) 1 is neutral, 2 is positive, and 3 is negative. b) 1 is positive, 2 is neutral, and 3 is negative. c) 1 is positive, 2 is negative, and 3 is neutral. d) 1 is negative, 2 is neutral, and 3 is positive.
