Two point charges Q and q are placed at distance r and `r/2` respectively alogn a straigt line from a third charge 4q. If q is in equilibrium determine `Q/q`.

Two free point charges +q and +4q are placed apart a distance x . A third charge is so placed that all the three charges are in equilibrium. Then

Two free point charges +q and +4q are placed apart a distance x. A third charge is so placed that all the three charges are in equilibrium. Then

Two poit charges of charge values Q and q are placed at a distance of x and x/2 respectively from a third charge of charge value 4q, all charges being in the same striahgt line. Calculate the magnitude and nature of charge Q, such that the net force experienced by the charge q is zero.

Two point charges +q and -q are placed a distance x apart. A third charge is so placed that al the three charges are in equilibrium. Then

Two point charges +q and -q are placed a distance x apart. A third charge is so placed that at the three charges are in equilibrium. Then
