A charge of magnitude `10^(-6)` C is placed at the origin. There are two points `P(sqrt3, sqrt3)` and `Q(sqrt6,0)`. Find potential difference between point P & Q.

Find the distance between the points P(-6,-3) and Q(-1,9) .

An electric charge 10^-3muC is placed at the origin (0, 0) of X-Y co-ordinate system. Two points A and B are situated at (sqrt2, sqrt2) and (2, 0) respectively. The potential difference between the points A and B will be

Two point charge q_(1) = -10xx10^(-6) C " and "q_(2)=15xx10^(-6) are 40 cm apart as shown in figure. Find the potential difference between the point P and Q.

2 mu C charge is shifted from "P" to "Q" .If workdone by external force in this process is 160times10^(-6) joule,then potential difference between points "P" and "Q" i.e. V_(P)-V_(Q) is

A charge q_(1) = 2.00 mu C is located at the origin , and a charge q_(2) = - 6.00 mu C is located at ( 0,3.00 ) m . (a) Find the total electric potential due to these charges at the point P hose coordinates are ( 4.00,0) m . ( b) Find the change in potential energy of the system of two charges plus a charge q_(3)= 3.00 muC as the latter charge moves from infinity to point P .

Two point charges -Q and +Q/sqrt(3) are placed in the xy plane at the origin (0,0) and a point (2,0) resp as shown in figure. This results in an equipotential circle of radius R and potential V=0 in the xy plane with its center at (b,0). All lengths are measured in meters. The value of R is ....m
