The electric force due to a uniform external electric field causes a torque of magnitude 16.0 ×× 10−9−9 N⋅mN⋅m on an electric dipole oriented at 30∘∘ from the direction of the external field. The dipole moment of the dipole is 8.5 ×× 10−12−12 C⋅mC⋅m. What is the magnitude of the external electric field? If the two particles that make up the dipole are 2.5 mm apart, what is the magnitude of the charge on each particle?
