An accelerating voltage of 2.36 x 10³ V is applied to an electron gun, producing a beam of electrons originally traveling horizontally north in vacuum toward the center of a viewing screen 37.9 cm away. (a) What is the magnitude of the deflection on the screen caused by the Earth's gravitational field? (b) What is the direction of the deflection on the screen caused by the Earth's gravitational field? up down east west (c) What is the magnitude of the deflection on the screen caused by the vertical component of the Earth's magnetic field, taken as 20.0 μT down? east m (d) What is the direction of the deflection on the screen caused by the vertical component of the Earth's magnetic field, taken as 20.0 µT down? north south west mm (e) Does an electron in this vertical magnetic field move as a projectile, with constant vector acceleration perpendicular to a constant northward component of velocity? Yes No O No (f) Is it a good approximation to assume it has this projectile motion? Yes…

A mass spectrometer is being used to separate common oxygen-16 from the much rarer oxygen-18, taken from a sample of old glacial ice. The ratio of the masses of these two ions is 16 to 18, and the mass of oxygen-16 is 2.66×10^−26 kg. They are both singly charged, and they both travel at 4.84×10^6 m/swhen they enter the mass spectrometer with a 1.11T magnetic field that is perpendicular to the particle velocity. What is the separation between their paths, in meters, when they hit a target after traversing a semicircle?

In a physics demonstration, two long parallel wires are separated by a distance of 2.15 cm. One wire carries a current of 1.70 A while the other carries a current of 3.35 A. The currents are in the same direction. (a) What is the magnitude of the force per unit length (in N/m) that one wire exerts on the other? N/m (b) Is the force attractive or repulsive? O attractive O repulsive O The magnitude is zero.

Two long straight wires carrying equal currents are perpendicular to one another (they are insulated).  Describe the forces between them?  If the wires are free to move which way do they move due to this force?

a) A DC power line for a light-rail system carries 900 A at an angle of 29.5° to the Earth's 4.96 x 10-5 T field. What is the force on a 100-m section of this line?
