An electric dipole consists of charges ±2.0 x 10-8C separated by a distance of 2.0 x 10-3 m. It is placed near a long line charge of linear charge density 4.0 x 10-4C m-1 as shown in the figure, such that the negative charge is at a distance of 2.0 cm from the line charge. The force acting on the dipole will be
- a)7.2 N towards the line charge
- b)6.6 N away from the line charge
- c)0.6 N away from the line charge
- d)0.6 N towards the line charge
Correct answer is option 'D'. Can you explain this answer?

An electric dipole consists of charges±2.0 x 10-8C separated by...
The electric field at a distance r from the line charge of linear density λ is given by
E = λ/2πε0r
Hence, the field at the negative charge,
E1 =
The force on the negative charge, F1 = (3.6 x 108) (2.0 x 10-8) = 7.2 N towards the line charge
Similarly, the field at the positive charge,
i.e., at r = 0.022 m is E2 = 3.3 x108 N -1
The force on the positive charge,
F2 = (3.3 x 108) x (2.0 x 10-8) = 6.6 N away from the line charge.
Hence, the net force on the dipole = 7.2N - 6.6N = 0.6 N towards the line charge.
E = λ/2πε0r
Hence, the field at the negative charge,
E1 =
The force on the negative charge, F1 = (3.6 x 108) (2.0 x 10-8) = 7.2 N towards the line charge
Similarly, the field at the positive charge,
i.e., at r = 0.022 m is E2 = 3.3 x108 N -1
The force on the positive charge,
F2 = (3.3 x 108) x (2.0 x 10-8) = 6.6 N away from the line charge.
Hence, the net force on the dipole = 7.2N - 6.6N = 0.6 N towards the line charge.

An electric dipole consists of charges±2.0 x 10-8C separated by...
An electric dipole consists of two charges of equal magnitude but opposite sign, separated by a distance. These charges can be either positive and negative or negative and positive. The magnitude of the charges is usually denoted as q, and the separation distance between them is denoted as d. The electric dipole moment, represented by the symbol p, is defined as the product of the magnitude of the charge (q) and the separation distance (d), and it points from the negative charge to the positive charge.
The electric dipole moment is a vector quantity, meaning it has both magnitude and direction. Its direction is from the negative charge to the positive charge. The magnitude of the dipole moment can be calculated using the formula p = qd.
Electric dipoles are important in various areas of physics, including electromagnetism and quantum mechanics. They play a crucial role in understanding phenomena such as polarization, electric fields, and interactions with external electric fields. Electric dipoles can experience torque when placed in an electric field, which gives rise to interesting behaviors and applications in devices such as electric motors and antennas.
