A molecule may act as an electric dipole, made up of two point charges of equal magnitude and opposite sign, with a constant separation between them. As shown, the molecule enters a vertical uniform electric field while moving with steady horizontal velocity. The molecule’s positive and negative charges enter the field simultaneously. What is the effect of the electric field on the velocity of the molecule?
- Ahorizontal component of velocity constant; vertical component of velocity increases
- Bhorizontal component of velocity constant; vertical component of velocity zero
- Chorizontal component of velocity increases; vertical component of velocity increases
- Dhorizontal component of velocity increases; vertical component of velocity zero
