A molecule can be modelled as an electric dipole made up of two equal point charges with opposite sign, separated by a fixed distance. As shown, the molecule enters a vertical uniform electric field while travelling with constant horizontal velocity. The positive and negative charges of the molecule enter the field simultaneously. Which row gives the velocity of the molecule in the field?
- 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
