Question

Question 19 (1 points) Three charged particles lie along the x-axis. One particle has a charge 9,=+15°C and is located at x=2m and another particle has charge 42=+6PC and is at the origin. Where on the x-axis can a particle with negative charge qz be placed such that the resultant force on it is zero? Select the correct answer O x=0.77m Ox=1.53m O x=1.23m O x=0.47m O Not enough information No answer submitted Scroll to N Top Contents Back Review Phys1B 0

Answer 1

Question in wo xolo Here qo e Here 8 = 5.44 m is not possible as a must be so & <2 is a negative charge. Negative charge attracte positive charges, So, if q3 is put for xy2m, then both q, &q. attracts it & it won't be stable. Again, if put q3 is put at x com, then both q, & q2 altracts it & it won't be stable either. So, only place where q3 is stable is in blo 2 positive charges, in that case, q, attracts q3 leftwards 93 at soetz q3 rightwards & thereby at a position in o e X<2, a stable position will be there where there 2 will be equal. sa ket's say dist. from a 1 So, force on. q> (6) + should be equal to o.
