Problem 13 :-
In figure 21-26 in attached file 3 particle 1 of charge +1.0 uC and particle 2 of charge
-3.0 uC are held at separation L = 10.0cm on an x axis.
If particle 3 of unknown charge (q3) is to be located such that the net electrostatic force on it from particles1 and 2 is zero.
What must be the (a)x axis and (b) y axis co-ordinates of particle3??

Problem 8.
In figure 22-30 in attached file 4 particle 1 of charge q1= -5.00q and particle 2 of charge +2.00q are fixed to an x axis.
(a) As a multiple of distance L, at what coordinate on the axis is the net electric field of the particles zero?
(b) Sketch the electric field lines.

Problem 26.
Charge is uniformly distributed around a ring of radius R= 2.40cm and the resulting electric field magnitude E is measured along the ring's central axis (perpendicular to the plane of the ring).

At what distance from the ring's center is E maximum?

1. When are electrostatic forces attractive? When are they repulsive? How is this different from gravitational force?
2. What does it mean to say that electrostatic forces are central forces?
3. What is the relationship between the magnitude of the force and the inverse square of the separation?
4. What happens to the m

An equilateral triangle has sides of 0.12 meters. Charges of -8.6, +8.0 and +1.6 micro Coulombs are located at the corners of the triangle. Find the magnitude of the net electrostatic force exerted on the 1.6 micro Coulomb charge.

You and a friend are spending the weekend making up missed lab experiments. You are on to second semester material and are studying the electrostatic interaction of two charges. You notice that two charges are exerting a certain force on one another. If the distance between two electric charges doubles, then the force they exert

When we model proteins on the computer, we must assign a partial charge to each of the non-ionized atoms. Let's consider the hydrogen bond between a carbonyl oxygen with a partial charge of -0.5 and an amino hydrogen with a partial charge of +0.3. The distance between these atoms is typically about 2A. Calculate the electrost
