Electrostatics of Conductor
Electrostatics of Conductor - All materials are broadly classified into two categories, one conductors and other insulators. When a conductor is placed in a electric field, there is a large scale of physical movement of free electrons, within the conductor and they move out only if we mak..
Electrostatic Potential
The electrostatic potential is defined as the work done in bringing a single positive charge from infinity to a point (Any point outside the electric field or space is called infinite point). The unit of potential is volt (symbol V..

Question : also, what do i plug in to the formulas?
1. If a neutral lucite rod is rubbed w/wool and gets a charge of -4x10^-6 C, whats the charge on the wool?
2. If a point charge of .008 C is brought .5 m away from a second point charge of .07 c, what is the replusive force acting on the first point charge? What will it be on the second one?
4. If a neutral object loses 1000 electrons, what will it have a charge of in terms of coulombs?
5. The attractive force btw a lucite rod and the wool use..
Answer : I'll just give you the relevant equation or principle. 1. Conservation of charge 2. F = kq1q2/r^2 4. 1 elementary charge = 1.6022E-19 C 5. use 2 with q^2 substituted for q1q2, solve for q 6. use 4 7. p+ and e- are both elementary charges so use 4 to find q; use 2 with q^2 substituted for q1q2, solve for r Note k = 8.98755E-9 Nm^2/C^2

Question : A charge of +q is located at the origin, while an identical charge is located on the x axis at x = 0.45 m. A third charge of +5 q is located on the x axis at such a place that the net electrostatic force on the charge at the origin quadruples, its direction remaining unchanged. Where should the third charge be located? Thanks!
Answer : Using F = k*q/r^2, the force between the charge at the origin and the charge at x = .45 m is: F = [ (8.99x10^9 Nm^2/C^2 * q) / (.45 m)^2 ] = q*(4.44x10^10 N/C^2). The third charge should be located to the left of the charge at the origin. Solve for r to find the distance. r = Square Root of [ (8.99x10^9 Nm^2/C^2 * 5q) / (4.44x10^10 N/C^2 * q) ] = 1.01 m to the left
