SUMMARY
The discussion centers on calculating the magnitude of an electric field exerted on an electric dipole formed by point charges +4.70 and -4.70 separated by 3.90 mm. The torque exerted on the dipole is given as 7.00×10-9 Nm, with the angle between the electric field and the dipole axis specified as 37.0 degrees. The correct calculation using the formula τ = d(sinθ)qE leads to an electric field strength of 634.6 N/C when sin(37) is applied, correcting an earlier miscalculation that incorrectly used sin(30).
