QB (1 point) o P A circular disk carries a uniform positive charge density 11 across its surface. An electrical dipole is placed along the disk's axis, with its dipole moment vector oriented as shown in the diagram. The disk's radius is very large compared with the distance from the dipole to the disk. How does the dipole respond? The dipole rotates, but its centre of mass does not move. The dipole does not rotate, but accelerates away from the disk The dipole doesn't move at all. The dipole both rotates and accelerates away from the disk. The dipole does not rotate, but accelerates toward the disk Q7 (1 point) 2d EA A. A bar, very long compared to the distances d and 2d shown, is electrically charged with a uniform linear density. The electric field vector at the point A is shown. Copy the diagram and draw the electric field vector at point B, scaled correctly compared to the vector at A
