Oct 01, 2008· *Please Help* - A small nonconducting ball of mass 1.0mg and charge q=(2.0x10^-8) C hangs from an insulating thread that makes an angle theta=30 with a vert. uniformly charged nonconducting sheet. Considering the gravitational force on the ball and assuming the sheet extends far vertically up and down, calculate the surface charge density.

Feb 27, 2017· A solid ball of radius r b has a uniform charge density ρ.-----PART A: What is the magnitude of the electric field E(r) at a distance r>r b from the center of the ball? Express your answer in terms of ρ, r b, r, and ϵ 0. SOLUTION: Since a charge density is given, the charge must be acquired from this density. A density has the units ...

Question:.Two Identical Steel Balls Mounted On Wooden Posts Initially Have Different Amount Of Charge As Follows.The Balls Are Allowed To Touch And Then Are Separated Again. What's The Final Charge On Each Ball In Each Case? A) One +3 C And The Other +15 IC B) One +12 C And The Other-4 0C 2One Positive Charge And One Negative Charge, Each Of Magnitude 4x106 ...

Ball Weight and Density How much will a ball of a given diameter in a certain material weigh? The answer is calculated by multiplying the volume of the ball by the density of the material. $text"Weight" = text"Volume" ⋅ text"Density"$ For example, calculate the weight of a two inch diameter lead ball: $text"Volume" = {4 ⋅ π ⋅ R^3 }/ 3$

Sep 07, 2019· Want to let the steel ball move upwards at a uniform speed, how is the torque of the spiral tube calculated? The parameters can be assumed by themselves. **The spiral tube is fixed on the central shaft, the central shaft is mounted in the ball bearing, and the thrust F .

Apr 17, 2018· The electrical charge that runs through anything, from an AA battery to a lightning bolt, is measured in coulombs. If you know the current flow in a circuit and how long it flows for, you can calculate the electrical charge in coulombs.

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge .

steel balls in a ball mill, or large lumps of ore in an autogenous mill or a mixture in a semi-autogenous mill, as well as the slurry that makes up the operating charge. Let Jt be the fraction of the mill volume that is occupied by the total charge, Jb the fraction of the mill volume that is occupied by steel balls and E the voidage of the balls

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case".
