1.	Two point charges of `+16 muC and -9 mu C` are placed 8 cm apart in air. Determine the position of the point at which the resultant electric field is zero.
Answer» Correct Answer - 24cm to the right of `-9 muC` charge Let E = 0 at a distance x to the right of `-9 mu C` charge , Use `k (q_(1) xx1)/((8+x)^(2)) = (k q_(2)xx1)/(x^(2))`
