Show hintHide hint
Think about how charges interact.
Question 2.
What is a dipole moment?
Show hintHide hint
Consider the charge and distance separating the charges.
3Question 3.
What defines the direction of an electric dipole?
- From positive to negative charge
- From negative to positive charge
- Random direction
Show hintHide hint
Consider how electric field lines point from positive to negative charges.
4Question 4.
In which orientation does a dipole experience maximum torque?
- True
- False
Show hintHide hint
Think about how torque is defined.
Question 5.
Determine the torque acting on an electric dipole with a dipole moment of 2 × 10^-6 C·m, oriented at an angle of 60° in a field of strength 5 × 10^3 N/C.
Show hintHide hint
Use the torque formula τ = pE sin(θ).
Question 6.
If an electric dipole is rotated from an aligned position to a position perpendicular to the electric field, calculate the change in torque experienced if the dipole moment is kept constant.
Show hintHide hint
Recall what happens to torque when the angle changes from 0° to 90°.
