The electric potential V at any point (x, y, z), all in meters in space is given by V = 4x². VoltThe electric field at the point (1, 0, 2) in volt/meter is

Three charges, each +q, are placed at the corners of an isosceles triangle ABC of sides BC and AC, 2a. D and E are the mid points of BC and CA. The work done in takinga charge Q from D to E is

The electric field created by a point charge falls with distance r from the point charge as

An electric dipole when placed in a uniform electric field E will have minimum potential energy, if the positive direction of dipole moments makes the following angle with E

The electric potential at a point on the axis of an electric dipole depends on the distance r of the point form the dipole as

An electric dipole is kept in non-uniform electric field. It experiences

An electric dipole consisting of two opposite charges of 2 × 10^–6 C each separated by a distance of 3 cm isplaced in an electric field of 2 × 10⁵ N/C. The maximum torque on the dipole will be

An electron dipole is placed along the x–axis at the origin O. a point P is at a distance of 20 cm from this origin such that OP makes an angle θ with the x–axis, the value of θ would be
