Answer:A
If a non-polar substance is placed in an electric field, what will happen?
A. A net dipole moment will be observed B. The substance will oscillate C. The substance will orient itself perpendicular to the electric field D. It will conduct electricity
Explanation: A non-polar substance consists of a huge number of dipoles in it, but they are oriented randomly and hence the net dipole moment of the substance becomes 0 and it acts as a non-polar substance. But if it is placed in an electric field, the dipoles present in it will orient themselves in the direction of the field and hence a net dipole moment will be observed, known as induced dipole moment. No current flow or oscillation of the substance will be observed.
