What is the force between two small charged spheres having charges of 2 xx 10^(-7)C and 3 xx 10^(-7)C placed 30 cm apart in air ? |

Answer» Solution :`F = k(q_(1)q_(2))/(r^(2))` `F = (9 XX 10^(9))(2 xx 10^(-7))(3 xx 10^(-7))/(0.3)^(2)` `F = 6 xx 10^(-3)` N Here, two given charges are like charges and so above FORCE is repulsive. |
