10.0 pJ of energy is stored in a 3.00 cm × 3.00 cm × 3.00 cm region of uniform electric field.
What is the electric field strength?
Homework Answers
V = 3 cm * 3 cm * 3 cm = 27 * 10-6 m3
E = sqrt [2 U / e0 V]
= sqrt [2 * 10 * 10-12 / 8.85 * 10-12 * 27 * 10-6]
electric field strength = 289 N/C

Two small spheres, each of mass 3.00 g, are suspended by light strings 10.0 cm in length (Fig. P23.62). A uniform electric field is applied in the x direction. The spheres have charges equal to -9.00 × 10-8 C and 9.00 × 10-8 C. Determine the electric fleld that enables the spheres to be in equilibrium at an angle of θ 11.0° Your response differs significantly from the correct answer.

Compare the electric energy that can be stored in a capacitor to the magnetic energy that can be stored in an inductor of the same size (that is, the same volume). For the capacitor, assume that air is between the plates; the maximum electric field is then the breakdown strength of air, about 3 MV/m. The maximum magnetic field attainable in an ordinary solenoid with an air core is on the order of 10 T. uE /uB = __× 10^__
