- An infinite number of charges,each of magnitude q,are placed along X-axis at X=1m,2m,4m,8m,16m and so on but the consecutive charges are of opposite sign starting with +q at x=1m. a point charge q’, kept at the origin ,experiences a force of what magnitude?
- four point charges,each +q,are fixed at the corners of a square of side ‘a’. another point charge q’ is placed at a height ‘h’ vertically above the centre of square,assuming the square to be in horizontal plane. what is the magnitude of force experienced by q’?
