解析 DAns: DThe forces due to the charges at different positions are shown.At , the force due to the negative charge is always much larger than the sum of force due to the 2 positive charges . Hence, there is a net downward force. ...
Two point charges q and - q are located at points (0 , 0 , - a ) and (0 , 0 , a) respectively : (a) Find the electrostatic potential at (0 , 0 , z) and ( x, y , 0). (b) How much work is done in moving a small test charge from the point (5 , 0 , 0 , ...
Three point charges (q, -2q, q) are located on a straight line with separation a as shown in the figure. a. Find the electric potential in terms of Legendre polynomials at any point in space in the absence of the grounded shell 4Z b...

Hello, I reasoned by simmetry, the two charges with value 2q not contributed at field because there are equidistant at point and are similar charges. Therefor only survival the field due to Q, using the definition for electric field of the puntual charge: E→(0,0)=−2Qkd2x^−2Q...

Abstract The rate of β-decay is affected by the charges, Q, of the nucleon's constituent quarks. The Salam–Weinberg scheme permits us, in a spirit of adventurous naivety, to conclude that Q̄ = 0.20±0.10; this combines with electron and neutrino data to suggest individual quark charge...
Here is the measure of the distance of the point P between the charge and is the unit vector having the direction same as that of direction of to the point p. Now let us think that the locations of the point charges q1, q2, q3……., qn in space are r1, r2, r3…...
