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??
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.
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?
