A positive charge `+q_(1)` is located to the left of a negative charge `-q_(2)` On a line passing through the two charges, there are two places where the total potential is zero. The reference is assumed to be at infinity The first place is between the charges and is 4.00 cm to the left of the negative charge. The second place is 7.00cm to the right of the negative charge if `q_(2)=-12muC` , what is the value of charge `q_(1) in muC`

A point charge Q is placed at the midpoint of a linejoining two charges, 4q and q if the net force on charge q is zero, the Q must be equal to :

Two point charges Q_(1) and Q_(2) are positioned at points I and 2. The field intensity to the right of the charge Q_(2) on the line that passes through the two charges varies according to a law that is represented in the figure. The field intensity is assumed to be positive if its direction coincides with the positive direction on the x-axis. The distance between the charges is l. (a) Find the sign of each charge (b) Find the ratio of the absolute values of the charges |(Q_(1))/(Q_(2))| (c) Find the value of b where the field intensity is maximum [(a) Q_(2) is negative and Q_(1) is positive (b) ((l +a)/(a))^(2) , (c) (l)/(((l+a)/(a))^(2//3)-1)]
