Final answer:
To calculate the torque on an electric dipole in a uniform electric field, use the formula τ = pE × sin(θ), where τ is torque, p is the dipole moment, E is the electric field strength, and θ is the angle between the dipole moment and the electric field. The dipole moment p equals Qd, where Q is charge and d is distance between charges. Without knowing Qd, we cannot calculate the exact torque value.
Step-by-step explanation:
Calculating Torque on an Electric Dipole in a Uniform Electric Field
When an electric dipole is placed in a uniform electric field, it experiences a torque which tends to align it with the direction of the field. The magnitude of this torque (τ) can be calculated using the formula:
τ = pE × sin(θ)
where p is the dipole moment, E is the electric field, and θ is the angle between the dipole moment and the electric field direction. Given that the charge Q is 4.0 μC and the distance between the charges d is not provided, we assume Qd atts the dipole moment. The electric field E is given as 1.0×106 N/C, and the dipole is rotated by 60° from the direction of the field. Using the formula, we have:
τ = Qd × E × sin(60°)
The exact value of Qd (dipole moment) is needed to calculate the torque. However, if we were given Qd, we could insert it into the formula to find torque. Without it, we cannot provide the numerical torque value. Thus, to answer, more information is required.
Note: Torque is the moment of force causing the dipole to rotate in the presence of the electric field.
