Electric Charge and Electric Field - pstcc.edu

Again, k is called the Coulomb's constant. Its value is k = 8.99x10 9 Nm 2 /C 2. The unit for electric field is N/C.. The way the electric field strength (E) of a point charge q weakens with (r) is like the way light intensity weakens as we move away from a light bulb. Suppose you have built an empty sphere out of glass that has a surface area of 1 ft 2 and has a tiny light bulb at its center.

Finding the magnitude of the magnetic force? | Yahoo Answers

Mar 15, 2010 · A metal ball having net charge 8.9e-6 C is thrown out of a window horizontally at a speed 47 m/s. The window is at a height 89 m above the ground. A uniform horizontal magnetic field of magnitude 0.03 T is perpendicular to the plane of the ball's trajectory. Find the magnitude of the magnetic force acting on the ball just before it hits the ground.

Ball mill - Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.
