Question

Which of these statements about a dipole are correct? Select all that are true.

a. The electric field at any location in space, due to a dipole, is the vector sum of the electric field due to the positive charge and the electric field due to the negative charge.
b. At a distance d from a dipole, where d >>5 (the separation between the charges), the magnitude of the electric field due to the dipole is proportional to 1/d^2
c. At a distance d from a dipole, where d >> 5 (the separation between the charges), the magnitude of the electric field due to the dipole is proportional to 1/d^2
d. A dipole consists of two particles whose charges are equal in magnitude but opposite in sign.
e. The net electric field due to a dipole is zero, since the contribution of the negative charge cancels out the contribution of the positive charge.

a. I
b. II
c. III
d. IV
e. V

Answer 1

• The electric field at any location in space, due to a dipole, is the vector sum of the electric field due to the positive charge and the electric field due to the negative charge.

• At a distance d from a dipole, where d >> 5 (the separation between the charges), the magnitude of the electric field due to the dipole is proportional to 1/d^3

• A dipole consists of two particles whose charges are equal in magnitude but opposite in sign

Step-by-step explanation:

A dipole is a pair of magnetized, equal or oppositely charged poles the are being separated by a distance.

The statements about a dipole that are correct are:

• The electric field at any location in space, due to a dipole, is the vector sum of the electric field due to the positive charge and the electric field due to the negative charge.

• At a distance d from a dipole, where d >> 5 (the separation between the charges), the magnitude of the electric field due to the dipole is proportional to 1/d^3

• A dipole consists of two particles whose charges are equal in magnitude but opposite in sign
