Question

Two charges + 3.2 x 10^-19 C and --3.2 x 10^-19 C placed at 2.4 Å apart to form an electric dipole. lt is placed in a uniform electric field of intensity 4 x 10⁵ volt/m. The electric dipole moment is ______.

Options

• 15.36 x 10^-29 coulomb x m

• 15.36 x 10^-19 coulomb x m

• 7.68 x 10^-29 coulomb x m

• 7.68 x 10^-19 coulomb x m

Answer 1

Two charges + 3.2 x 10^-19 C and --3.2 x 10^-19 C placed at 2.4 Å apart to form an electric dipole. lt is placed in a uniform electric field of intensity 4 x 10⁵ volt/m. The electric dipole moment is 7.68 x 10^-29 coulomb x m.

Explanation:

Dipole moment p = q (2l)

= 3.2 X 10^-19 X (2.4 x 10^-10)

= 7.68 x 10^-29 Cm
