A short electric dipoleis placed along y-axis at the origin. The electric field vector at a point P on x-axis is vec(E ) _(1) . The dipole is rotated by ( pi)/(2) at its positin . Now, the electric field vector at point P is vec(E )_(2) . Select the correct alternative(s) :

Two short electric dipoles of moment P and 8P are placed in opposite direction on a line at a distance of 15cm .The electric field will be zero at point between the dipoles whose distance from the dipole of moment P is?

A short magnetic dipole when placed at origin with its dipole moment oriented along x-axis , the magnetic field at the point (a,0) is vecB . What will be the magnetic field at the above point , if another identical dipole is also placed at origin with its dipole moment oriented along y-axis ?
