AIEEE 2006 Mock Test

An electric dipole is placed at an angle of $30^{\circ }$ to a non-uniform electric field. The dipole will experience:

A material $B$ has twice the specific resistance (resistivity) of $A$. A circular wire made of $B$ has twice the diameter of a wire made of $A$. For the two wires to have the same resistance, the ratio $L_A/L_B$ of their respective lengths must be:

Kirchhoff’s first law ($\sum i=0$) and second law ($\sum iR=\sum E$) are respectively based on the conservation of:

In a region, steady and uniform electric and magnetic fields are present. These two fields are parallel to each other. A charged particle is released from rest in this region. The path of the particle will be a:

Needles $N_1,N_2$ and $N_3$ are made of a ferromagnetic, a paramagnetic and a diamagnetic substance respectively. A magnet when brought close to them will:
