दो आवेश -q और +q बिंदु A (0,0, -a) और B (0,0, a) पर स्थित हैं। परीक्षण आवेश को बिंदु P (7, 0, 0) से Q(-3,0, 0) तक चलाने में कितना कार्य करना पड़ेगा?

|(a,p,q),(0,b,r),(0,0,c)|

Two charges - q and + q are located at points A(0, 0, - a) and B(0, 0, + a) respectively, work done in moving small test charge from point P(7, 0, 0) to Q(- 3, 0, 0) is ...... .

[[ 0 , p-q , p-r ],[q-p , 0 , q-r],[ r-p , r-q , 0 ]] =

Two charges -q and + q are located at points A (0, 0, -a ) and B(0, 0 + a ) . How much work is done in moving a test charge from point (b, 0, 0 ) to Q (-b, 0, 0) ?

Is P(7,0) and Q (0,7) represent the same point ?

Two charges - q and + q are located at points A(0,0, -a) and A(0,0, + a) respectively. How much work is done in moving a test charge from point P (7,0,0) to Q(-3,0,0)?

If P = (0,1,2) and Q = (4,-2,1), O = (0,0,0) then P hat O Q =
