Please help me with these questions with detailed explanation!

Problem: Atom A is easier to polarize than atom B. Which atom, A or B, would experience a greater attraction to a charged rod a distance away? O Atom A O Atom B o Same (the polarization does not matter) O There isn't enough information (depends on charge) Problem: In an old-style television picture tube (not in a modern flat-panel TV) electrons are boiled out of a very hot metal filament placed near a negative metal plate (see the figure). These electrons start out nearly at rest and are accelerated toward a positive metal plate. They pass through a hole in the positive plate on their way toward the picture screen. If the high- voltage supply in the television set maintains a potential difference of 13100 volts between the two plates, what speed do the electrons reach? (You can use the nonrelativistic approximation here. Rest mass of the electron is 9.11 x 10 31 kg) Plate Plate Hot Manwont bo= 0 3.01 x 10' m/s 3.01 x 10' m/s 0 4.80 x 10' m/s 0 6.78 x 10' m/sProblem: A neutral hydrogen atom is near two charged particles as shown. What is the direction of the net force on the hydrogen atom? H B +q G C H D F E Direction H O Direction C o Direction G o Direction E O Direction B Problem: The magnitude of the electric field due to a disk of radius 3 m and a uniformly distributed positive charge is measured to be 150 N/C at a location in the air 6 mm from the center of the disk, along a line perpendicular to the disk. Approximately what is the magnitude of the electric field due to the disk at a location 9 mm from the center of the disk, on the same line? 0 44 N/C 0 506 N/C 338 N/C 0 67 N/C O 150 N/C
