Dipole Moment Questions

Three-point charges $+q$, $-2q$ and $+q$ are placed at points $(0,a,0)$, $(0,0,0)$ and $(a,0,0)$, respectively. The magnitude and direction of the electric dipole moment vector of this charge assembly are:

A bar magnet of length $l$ and magnetic dipole moment $M$ is bent in the form of an arc subtending $60^{\circ }$ at the center. The new magnetic dipole moment will be:
