Two point like charges having magnitude =16 muCand -9muC are separated by a distance 10 cm in air. The resultant electric field will bt zero at distance......from -9muC charge. |

Answer» 30 cm `therefore q_(1)/(x+10)^(2) =q_(2)/x^(2)` `therefore q_(1)/q_(2) =((x+10)/x)^(2)` `therefore 16/9 =((x+10)/x)^(2)` `therefore 4/3 =(x+10)/x` `therefore 4x = 3x + 30, therefore x = 30 cm` |
