FAQs on L 3 Electric field (Electrostatics ) - Torque on a dipole in uniform field Video Lecture - Additional Study Material for NEET

1. What is the definition of electric field in electrostatics?
Ans. The electric field in electrostatics is a vector quantity that represents the force experienced by a positive test charge placed at a particular point in space. It is defined as the force per unit positive test charge.
2. How is torque calculated on a dipole in a uniform electric field?
Ans. The torque on a dipole in a uniform electric field is calculated by multiplying the magnitude of the electric field by the product of the dipole moment and the sine of the angle between the dipole moment vector and the electric field vector.
3. What is a dipole in electrostatics?
Ans. In electrostatics, a dipole refers to a pair of equal and opposite charges separated by a small distance. The dipole moment is the vector quantity that represents the strength and direction of the dipole, and it is defined as the product of the charge magnitude and the separation distance between the charges.
4. How does a dipole behave in a uniform electric field?
Ans. In a uniform electric field, a dipole experiences a torque that aligns it with the field. The positive charge of the dipole experiences a force in the direction of the field, while the negative charge experiences an equal and opposite force. This creates a net torque that tends to align the dipole with the electric field.
5. What factors affect the torque experienced by a dipole in a uniform electric field?
Ans. The torque experienced by a dipole in a uniform electric field depends on several factors, including the magnitude of the electric field, the dipole moment, and the angle between the dipole moment and the electric field vector. Higher electric field magnitudes, larger dipole moments, and larger angles result in greater torque on the dipole.
